HORUSDY 23pc 1/4" Ultra Low Profile Mini Ratchet Screwdriver Set – Tamper Resistant Star Bits, 90 Degree Right Angle Offset Reversible Drive Handle, High Torque Close Quarters Tool with Multi Hex Bits

This is a pretty good set though I will say, a set like this should come with some sort of case or stowable packaging. It's three parts at least and should be kept together as a set. The main part, the ratchet driver is pretty good. It's not too small and it has a good feel in the hand. The ratchet mechanism is solid.

Does not work under door knobs. Everything else seemed okay. My sole reason was to find something that worked under the door knob screw but this is not it.

Insanely useful for tight areas, I used this to easily reach a known stubborn T20 on my BMW F10's headlight module, and it will also come in handy if you work on Ford Escape Hybrids as this can easily get to the bolts on the side of the battery. One thing I will say is the ratcheting mechanism feels a bit stuff, it's tough to loosen and tighten if you don't hold your finger on the big gear. It may loosen up over time or just need to be lightly oiled.

It's a pretty good mini ratchet screwdriver set. I used it to change my car's air filter—that spot's a real pain—couldn't have done it with my other ratchets. This one was perfect. The ratcheting isn't super smooth, but it works. The bits aren't the toughest, might break on really stubborn screws. A case would've been nice. Still, it's great for the price.

Very good product and well made. I’d buy it again. Recommend.
