Is the 72-tooth ratchet worth it over a 36-tooth one?

Yes for tight work. A 72-tooth ratchet needs about 5 degrees of swing, so it engages where a coarser ratchet cannot turn. It is the main reason this set competes with finer-tooth rivals.

Does it cover both metric and SAE?

Yes. The set includes metric and SAE sockets, combination wrenches and hex keys, so it handles domestic and imported vehicles without a second set.

How does it compare with a GearWrench or Tekton set?

It matches them on tooth count and piece count and adds combination wrenches and hex keys in one case. Those brands offer stronger pro warranty support and sturdier cases, so choose them if the box itself matters more than coverage.

Ratchets, shallow and deep sockets, combination wrenches and hex keys in a molded storage case. It does not include a 1/2-inch drive set or a breaker bar.

Is it too heavy for a home garage?

It weighs about 10.2 kg, so it stays put on a bench or in a cart. It is fine for garage use but not ideal for carrying to jobs.

Is it suitable for professionals?

It is marketed for professionals and DIYers, and the tools hold up to regular shop use. The case is the weak point, so many pros move the tools into a tool chest.
