20-PCS Allen Key/Allen Wrench Drill Bit Set, Impact Hex Bits (Metric & SAE) 2 Inch Long, Premium S2 Steel, 1/4'' Hex - Shank, Magnetic Head, for DIY Furniture Assembly & Car Repairs, by DCWecher

Worked perfectly for working on my RC car. Bits seem to be decent quality and fit well in my Ryobi driver. I cannot speak to the longevity or the hardness, but worked very well for removing small screws from an RC chassis. Well worth the price.

Good tool you can use them on a ratchet screwdriver to remove towel bars. That’s one of the things I use it for.

as other reviewers have stated, some of the tolerances on the allen wrench tips are off by as much 20% on the smaller sizes. Most are very close - so am pleased. Others complained about duplicate or missing sizes - the set I received had each bit match the holder size label - so no issues there. The longer bits allow to work in tight places.

They are good, I like the fact that they are durable and having both SAE and metric is a good thing. Would buy again.

Good value for the money. Works as stated.

I was skeptical with how cheap these were, but so far I've been using them for a month or so at work and they've been exactly what I needed! Compact enough to fit in my smaller tool bag, and strong enough to handle working on conveyors

I don't think anyone can beat it in price and the quality is also solid.

Absolutely amazing. Used them the day they arrived. I ordered a bed from Amazon and it came a few days ago. There was a lot of screws and the bed came with Allen wrenches. I was NOT in the mood to make whole bed with just Allen Wrenches. That would have taken me hours. I have already gone through that before and was not in the mood now. Used these bits with the drill I already have and they work well. Made the whole bed in 1.5 hrs. If you have a drill these are a must have.
