OWAJ1300EA - Autoject 2 Fixed Needle Syringe Injector

This was a lifesaver for my small dog with thin skin diagnosed with diabetes. For the first month, she would let me manually inject her, but after a month, I could not get her to stay still; it was a huge fight. This auto-injector is fast, painless, and very easy to use; just pinch the skin and press the button. You do need to have a bit longer needle. I used a 12.7mm length. For pets, I highly recommend, just get it!

This is a game changer for anyone who afraid of needles. Highly recommend this item if you need to inject yourself with medication. This biggest challenge for this device is you have to find the right calibration for your syringe. If that changes, you need to adjust it so it doesn't wind up hurting you.

I cannot stand needles, injections, blood, or generally anything medical. This device is an absolute god send that works so well and makes me not have to fear injections. It works exactly as described and makes injections smooth and painless. Some tips that it took me a while to figure out: 1. The instructions list "compatible syringes" along with recommended dialing for those syringes. This device is compatible with any fix-tipped syringe and can be dialed in using the yellow plastic tool. Insert a syringe and launch it, then use the yellow tool to measure how far out of the end it sticks. 2. If you're buying this, you probably also have a fear of needles. I went for a 31 gauge needle but was worried about how long the injection would take with this small of a gauge. <10 seconds overall, and I truly barely felt it (and I'm a MASSIVE baby when it comes to all of this. Cannot recommend this product enough.

Was excited about buying this item because of the good reviews. Bought it to take a weekly injection into my leg. Even bought another set of luer lock needles that fit this device perfectly after figuring out the adjustment setting. The problem with this tool is the spring in this device seems to be way too strong. When you press the button to inject the medicine, this tool slams the plunger of the syringe down so hard that when you hear that click, the yellow symbol is shown in the window immediately. So immediately, that syringe was slammed all the way down using great force, instead of taking about 5-10 seconds or so to push it down like how you are supposed to do it. Due to that problem, this tool makes the syringe shoot the medicine all over the place at maximum force. I suppose a minimal amount of medicine gets injected, but most of it will be wasted because it will be all over your leg and all over the inside of the Autoject tool. The instructions provide an email address for the manufacturer, so I emailed the manufacturer to explain what is going on and ask if they can help me resolve the problem. Several days have gone by and they never bothered to reply. Guess I will be returning this for a refund then, since it doesn't work properly and there is no customer support.

Wow! Easier than I expected! I don’t have the right needles, but I was able to adjust it to mine. Then I tested to see the depth my needle came out before injecting which was enough. The actual injection was painless and fast. I definitely recommend this for GLP1 injections
