Rosewill Anti Static Wrist Strap Band, ESD Strap Anti Shock Wristband Bracelet with Grounding Wire Alligator Clip, Detachable Extra Long Cord (Packaging May Vary) - RTK-002

Fast shipping. This is a great product to have if you want to feel safer while protecting your expensive equipment. I was able to repair my computer confidently, knowing I had that extra layer of protection and was properly grounded.

The quality is fine, and it does what it needs to, at least as far as I can tell without any real means to test that assumption. One thing to point out is that the strap is not very long. So, if like me, you intend on strapping this around your ankle, you may find that difficult. I ended up extending the length with one of those hook and loop cable management straps and that worked out fairly well.

I've worn this every time I change something with my computer and have never had a problem with shocking my components! Whether newer components might be able to withstand being touched without a bracelet, it never hurts to be cautious. Very simple to use, just strap it on and clamp it to metal before working on your computer.

There are two types of damage that ESD can cause, immediate and latent, with latent being the most common type of damage we see today. A nice, good jolt of static electricity can really damage your PC components. As many Youtube videos prove that you would need a powerful jolt of static electricity to completely fry a computer component outright, other DIY videos on Youtube show that ‘real world’ testing by rubbing your feet on carpet and touching certain components like hard drives, ram, motherboards, etc. would not necessarily fry your component (they will still work), but what people do not realize is that these weaker jolts of static electricity still damage the components! You can search Youtube for the videos under, “Can Static Electricity Damage Computer Parts? Do You Really Need an Anti-Static Wrist Band?” for this demonstration. When an ESD event occurs, the charge surges into the semiconductor IC (integrated circuit), while the total energy transferred is small and the energy discharged is less than a micro second, the voltage is high, commonly up to 10 kV, but up to 25 kV can be reached (max potential achieved on human body). Low relative humidity may also increase the charge buildup. We may not be able to feel it, but to ICs, it is practically like a lightning striking. Note that static discharge below 3000 volts (3 kV) is not typically detectable by humans. Latent damage may not have completely destroyed the circuit and while the circuit may still complete (like the picture shown), the performance will be degraded. There will be higher resistance due to less conductive material along it’s path which can affect timing and signals, which can be critical for high speed communication, especially with todays smaller circuits. The damaged component will continue to operate at a degraded and possibly unstable level until failures start to occur. If you take an ESD course, you will be shown what static electricity does to components under 15,000x magnification. It is small, but the component layer gets punctured by the tiniest of zaps! IC pathways get annihilated! Over time, this damage will cause your component to cease operating. Just because you touch your computer component with static electricity and it still works, does not mean it has not been damaged. The damage is there! Everyone that says, “ESD is not true”, “I’ve built hundreds of computers and never used a strap and everything was always ok”, “I never use a strap because I’m careful and it has always worked” are all full of it. Avoid these people as these people never took the time to do their due diligence. ESD damage is a proven fact and ESD prevention are cost efficient and that is why every single respectable company dealing with components use some type of ESD control measure. From anti static bags to flooring to mats, wrist straps, chairs, ion generators, etc. People that do not use straps don’t kill components outright, but if the component did experience a ESD event, you can be certain that you have damaged it, degraded it and it will fail much sooner than it should. Latent ESD damage is not immediately noticeable because it is very subtle and microscopic, but the damage is there. So you may ask; what makes a good setup for a hobbyist or a home user? Get a proper anti-static wristband and an anti-static mat large enough for your computer equipment, tools and feet/chair. Avoid plastic / synthetic type clothing, make sure you are properly grounded through the wrist strap and make sure your computer and part you are going to install is on the anti-static mat. Another thing to remember is that you don’t need to necessarily touch the component to cause a ESD event, just being close to the component can cause damage. So yes, protect yourselves when handing delicate components! Even if you do not purchase this one, get one! Always properly attach the the chassis of the case (not paint) and make sure it is properly grounded (plug the computer that your wrist strap is attached to into the power outlet). I liked Rosewill’s ESD Anti-static wrist wrap mainly due to it’s price. The velcro was not intrusive and ok, though an elastic band may have been better but this was still comfortable after an hour of use. The metal snap allowed me to disengage and use the restroom. Google, "ESD ElectroStatic Discharge Tutorial", for complete information on ESD. Educate yourselves! To be clear, I attached a picture of microscopic damage from ESD. Hardly noticeable to the naked eye, but damage like this could weaken a circuit path, or outright do irreversible damage, eventually causing it to fail as the cumulative effects of thermal enlargement and contraction. A strong enough ESD event can also cause your hardware to cease functioning immediately which would indicate an "immediate" type ESD event, but most likely it will be "latent" type event.

I purchased this to use while building two gaming PCs from scratch. In the winter my house can get pretty dry and static shocks are not uncommon and even the smallest static discharge can destroy a motherboard, CPU, memory or many other components needed to build a computer from scratch. Yes there are other ways you can protect against static discharges, but with around $2000 per computer on the line, I wanted the best option available and IMO using a strap is the best option. I was an IT manager for over 20+ years and managed the team that deployed PCs in my company. Back in the day we did a lot of upgrades adding memory and graphics cards, etc., and I made it mandatory that everyone used a static strap. We rarely had a problem when following that protocol. That said, this one is very well made. The older models we used did not have the snap so you could not easily disconnect to walk away and then reconnect when working again. That is a nice feature. The cord is plenty long and easy enough to keep out of the way while working. You can remove the clip and use the plug to ground yourself to a surge suppressor or wall outlet. However, the easiest method and the one I normally use is to plug in the PC power supply to a grounded outlet and clip to the fan grill. Either way will work. Good quality for the money and a must have when working on sensitive electronic equipment.

Excellent wrist strap, BUT ONE PROBLEM. I bought it to wear every night when I sleep. It is part of my "grounding" or "earthing" program. I've been using an ELASTIC wrist strap for years, and it works great. The elastic is starting to give out and time to replace it for good electrical contact. This wrist strap uses Velcro. It is well done, and will work great for occasional use, but not every night, and during the night when having to get up. Trying to remove it and then put it back on, when half a sleep wound be too much. I measured the electrical resistance, and it measured 1.003 meg ohm, right on their specification. As an electronic engineer, it is nice to know that they used a decent resistor that meets their spec, but actually the value is not at all critical. Bottom line: Infrequent use, its great. Daily (especially "nightly") use, recommend an elastic band, not Velcro. By the way, the grounding is working great! Has eliminated untreatable back pain, and who knows what else?

Good product does what you expect it to do, pretty well !

I've been using this for a few months now. No issues, works as described. Definitely worth purchasing if you're doing any PC repair work.

Arrived (much) later than my other orders so I assembled the pc without using it, thus no idea if it is ok. Not sure about the connectivity from the clip to the wrist as well as I do not have a multimeter to test it. Either way, the item arrived in a sealed envelope and inside was the item itself housed in hard plastic cover and cardboard type of backing. Surprisingly, this was opened, almost 3/4 opened which didn't seem like the glue has worn off. So... this felt like a returned product by the previous person who purchased it and promptly repacked for a new order. Not sure whose fault it is, but I guess the packer / sender was betting that since I was an international customer I wouldn't be bothered to return this - which is correct, too much of a hassle to me... kudos to you...

Cumple con su cometido, es un muy buen brazalete y tiene el largo suficiente para maniobrar según lo deseado. He estado haciendo modificaciones a mis computadoras, y dicen algunos expertos que no es necesaria la pulsera anti estática, pero en cuestiones tan delicadas como el cambio de un procesador, o el manejo de otros dispositivos internos prefiero tener la confianza de poder manipularlos sin el temor de darle alguna descarga inconscientemente. Buen producto, y altamente recomendable si vas a hacer modificaciones a PC o a algún aparato delicado.

Venduto ad un ottimo prezzo, e fa perfettamente il suo dovere. La lavorazione sembra curata e i materiali resistenti. Il bracciale non è particolarmente scomodo, la pinza mi sembra ok, l'avvolgimento a molla del cavo forse è fin troppo elastico, ma non è un problema distenderlo per allungarlo.
