Re: flex heads DO NOT BUY THE 1/4in Stahlwille. I have two that were broken out of the bag after waiting since February (arrived a few weeks ago). The flex button pops out because the pin is too short. I need to make new pins, but I am lazy. 3/8 Stahlwille has been great. Use it all the time. Have not tried the 1/2in. Seems great, just arrived is the only reason I have not used it.
Long 1/2 flex head (for lug nuts and such): Gedore is the nicest I have. 60 tooth, locks in the center (won’t ratchet either way) for extra strength.
3/8: stahlwille is very nice. The Gedore 3/8 the head is too big (it’s the same as the 1/2 so if you want a small 1/2 flex head the Gedore is nice). Wera the head is big too and it is ball type. I have a capri too, it’s ok, but not quick release.
1/4: I have Proxxon and a gearwrench both seem fine, but I really like the Wera zyklops which is a ball end. Downside is that it is a bit bigger so it won’t work everywhere, but it is the one I grab. Gearwrench is very slim so if you want something to get anywhere, that should work well. I don’t like that gearwrench are not quick release.
I have been waiting for Hazet to release their flex heads with the 90 tooth, preferably quick release. All they have now is low tooth count. The Hazet 90 tooth should be the best and most durable. Doubt that they make a 1/4in one though. They will be expensive. If it’s an everyday use thing, I think they would be worth it.
Chads might have twingrip (they did for a while). Just checked and they seem to have the two component SBA (bubble package) for $40. KC is backorder. Amazon cancelled my and frank’s orders. Sometimes someone has one in stock on Amazon, but it’s $50 usually. I got two pair, but I want a third for the kitchen drawer.
