I realize this is an old thread, but I came across it looking for recommendation for ratcheting flex head wrenches.
I decided to go with an Olsa Tools set. 6 point, 120 tooth, 12 piece SAE set for $130 shipped. I'm a serious DIY guy and don't need top of the line, and was getting set to go with GW for inch (they have a 10-pc set with an 11/32" wrench which I use all the time( for $151 and a Husky 13 pc metric set (8-19mm and 21) for $110. However, the most recent GW reviews weren't good, so I continued my research. I came across Olsa. I have 3 Olsa flex-head socket wrenches which are pretty nice, so I thought I'd give these a try. They were less than the GW, too. I bought direct from Olsa and got points, so I'll use those to buy the metric set when they are in stock in August. I called Olsa (and got a live person, no phone tree), to check when they'd be in. I did it as a test to see how the customer service was.
I've used just one wrench, but it feels really nice. I thought the 6 point opening would be an issue, but the 120 tooth rotation mostly negates that.
The wrenches have an arrow indicating which way is loose and tight. Finish is nice, they feel "weighty" and the flex heads rotate really nice: not too loose or tight. The fit on the fasteners was nice and firm as well. They got here just a few days after I ordered them.
