Great for tight spaces.
I'm a sucker for dumb sets of tools and tools in general, but I typically wouldn't buy something like this - it just seemed redundant. That is until I started almost a full rebuild of my SUV. This included the full AC system and all gaskets, and in my specific model there are three notoriously terrible screws behind the engine, between it and the firewall. The way they're situated, the head is pointed at the firewall with about two or three inches of clearance behind them. Maybe put a bit into a socket that holds it snug and do it that way? Nope, even with a low profile ratchet you don't have nearly enough space. It's so notoriously bad that any videos or guides showing anyone working in this spot almost always suggest a tool exactly like this, and I very quickly went from "this is a gimmick" to "I can't live without it." I'm sure multiple companies make identical kits and I don't know if this is the best one, but it did not feel cheap and it got the job done. The case is nice and does its job. I had to apply pretty significant force and shove this in very tight areas, and the ratcheting mechanism never failed on me. I genuinely don't know how I would have removed certain screws without it, outside of lifting the engine up a foot or two. Seriously - this isn't expensive, and yeah, you might buy it and forget about it; but when you run into a screw that has only two inches of clearance you'll be thrilled to have this sitting in your toolbox ready to go. I probably wouldn't use this as a replacement for "normal" tools - only when actually required due to low clearance.

Important tool to have on hand.
Bought these because I couldn't get into the crack between the crossmember and the trans pan on my truck. Saw an install video and someone recommended a tool like it. Saved me because without it I had stripped a bolt doing it from an angle. This came in the mail and allowed 90° contact as well as ratcheting action. Get and keep in your tool chest.

Great size for tight spaces
This small tool set is a lifesaver in tight spaces. Wouldn't have been able to get the heat shields or tiny brackets off and back on my car without this set. What makes it good is how one side of the mini ratchet has a stop so the bits can't slide out the back. Nice selection of bits.

A+ CUSTOMER SERVICE
The ratchet is not good. The holder broke within days and doesn’t hold bits. You can buy the craftsman one for $15 and it’s 10x better. The bits are great and the case is great. But the ratchet sucks. Update - they offered me a full refund out of nowhere (2-3 months after I left review). I just got the refund today. This is exceptional customer service. Dont hesitate to buy from this brand.

Nice little tool, compact and handy.
The 90 degree ratchet lets you get into difficult spaces and there's a great selection of snap-ins. The handle is small which is an advantage in some cases (where you can't get a regular ratchet in the space) but does mean you have very limited leverage. Overall, a very nice tool, great value for the money.
