Hotop 26 Blades Stainless Steel Feeler Gauge Dual Marked Metric and Imperial Measuring Tool for Valves, Spark Plugs, Automotive Gaps(0.0015/0.04-0.025/0.635 Mm)

Great feeler gauges. They are accurate to what size they say. Only off a few .0001. Comes with a few 10 thou shims and a few 2 thou. Wish it came with more 10 and 2s as those are what I primarily use at work.

Well made and well worth the money

I was a bit hesitant seeing how cheap this was, but figured I would give it a try. I have digital calipers from a reputable manufacturer, so I figured I would just verify before I actually used it. Message to sellers/manufacturers: PEOPLE LIKE ME WOULD BUY BETTER IF OFFERED I don't want to pay $100+ for a feeler gauge set, but I'm not looking for the cheapest option either. I would really like to be able to buy a product like this and be able to trust that the claims on their product page would be honest.... Too many times have I been BURNED pretty hard on some purchases, but this one seems like it worked out.

Measurements were a reasonable "average" as the gauges aren't perfectly uniform thickness (expected with literally everything, just want to make sure people are aware). The majority of the gauges are just fine, some could definitely be better, but for the price, it's very difficult to complain, only that there isn't a more "premium" option with better tolerances available. There are other reviewers that claimed some of the gauges are way off, which I thought I had experienced as well, however, putting together my table, I noticed I didn't have all 32 gauges recorded. Some of the thinner gauges were just perfectly stuck behind other ones that I easily missed them trying to get measurements of them all (I thought I was being pretty careful too on my initial pass). Just try to make absolutely sure there aren't two of the super thin ones stuck together like I found about 4 pairs of. It's nothing bad about the manufacturer's process, it's just what happens with thin sheets of metal with oil on them.

I like it, it's east to use and find the right tab, I wish it had smaller sizes. But it does what is says it does, and functions well. the quality seems pretty good, and over all, worth the money.

Love the dual markings! Good product for the price - be forewarned, the item comes "oiled" and has to be cleaned....

These are excellent feeler gauges. There is a good amount of variety of the different sizes. Having the different sizes available for adjusting the valves on the motorcycle was very helpful. They are made of good quality metal and should last a long time. The thinner ones do allow for a slight bend to occur which is perfect for my valve adjustments. They get the job done. The little nut holding them together allows them to be easily removed. The blue plastic "holder" is a thin plastic and will likely rip easily, but that is not a concern to me. What's important is the quality of the tool itself and these work perfectly. They are very reasonably priced and I would Highly Recommend this product.

Found them to be on the money. ,ensured several and allweee spot on.

Great product. Had no explanation, but none was needed
