Harley Benton Feeler Gauges

This product is good quality and MUCH cheaper than getting feeler gauges from a luthier shop.

I like that fact that they show measurements in both inches and mm, which is something you don't get with feeler gauges from US luthier shops.

My only complaint is that there's simply too many feeler gauges in the set! I could easily get by with half as many thicknesses and some of the thinnest ones aren't really useful for guitars. This set doesn't really feel like a guitar specific product. But I guess it's kinda silly to complain about getting too much for the money!

Actually, there one more thing. I wish they were a little longer. But they work fine, just slightly fiddly in some situations so it's not really a big deal.

Highly recommended!

I've bought two of these; one for the measuring purposes and the other to make DIY nut files (the real nut files are terribly expensive and shamelessly overpriced, especially if you're only planning to use them once in a blue moon and there are a couple of videos on YouTube explaining how you can make them yourself out of the feeler gauges).

They come in a sort of a nylon/plastic sheath and as some of the other reviewers mentioned; they are drenched in some kind of oil, possibly to serve as a lubricant and/or to keep them from rust, so you'll likely need to keep a tissue at hand when taking them out, at least for the first several times of use, because it seems impossible to wipe it all just in one attempt.

I've used them several times now for measuring, they don't feel too flimsy and seem like they'll gonna last.They do seem a bit sharp on the edges, so be careful when handling them.

This feeler gauge works just like it should, it comes with all the measurements i needed to do a basic setup on my guitar. It has more thicknesses than what you'll need but I guess its better to have too many than too little.

Shows both inches and millimeters.

Its a good pair for the Harley Benton String Action Gauge if you really want to setup your guitar to your own liking.

Only downside was that it came very "oily", i had to spent 20-30minutes going over each size 2x or 3x times to clean up somewhat properly, I presume that oily substance is to prevent corrosion. Although it was annoying to clean I also have to say that it isn't the type of oil that is hard to remove.
