They have gotten good reviews and an overall rating of 4.5/5.0 on Amazon.

There is a lifetime warranty on their tools excepting those which have been damaged due to misuse.

Made out of titanium?

CPB · Jun 30, 2025

Mine appears to be chromed steel.

ORVietVet · Jun 30, 2025

Someone, on another forum said titanium steel and were lighter/stronger than the normal tool steel.

I'm using one of their zeal high tooth 3/8" ratchets.

Which one of these? The flex head one is twice the cost, at Amazon.

ORVietVet · Jul 1, 2025

This one is "slim" and 3 times the cost of the fixed head.

Here is another one for $66.

Mine's a 3/8" anvil inside a 1/4" body.

IIRC from the GarageJournal forum, that brand is supposed to be pretty good. I believe I have an extension or something that I ordered from Amazon a few years ago.
