Wera 6004 Joker M Wrench with Flexible Size Adjustment, 13-16mm

A little pricey but works great in tight spots where a ratchet wrench or socket wrench won't work. I use it for installing electric motors where there isn't much room between the mounting studs and bottom of motor.

I have seen reviews on certain sizes of the 6004 where the durability of this tool is questioned when applying force. I can say after about 6 months of regular use including reasonably high torquing of nuts and bolts this thing really holds up. Once you get the hang of it this wrench is ultra efficient because of the ratcheting mechanism and very handy considering it’s six sizes in one wrench. Plus it’s so well made and aesthetically pleasing I actually look forward to using it.

Great tool, small learning curve on how to operate it, intuitive like a normal wrench. I have yet to have it slip on tubing nuts and fasteners. Only time it did slip was on a pre-rounded nut. The grip is so good that you can hang it on the fastener and leave it there while you look for the other wrench you just had in your hand 10 seconds ago but takes you 30 seconds to find. This one was the most common size I use so it was a test before I went all in on some expensive wrenches. Build quality is top notch, I love the brushed finish.

The two smaller wrenches, the spring is too weak. On the larger sizes, this thing is awesome.

Great for tight spots

High quality tool. I like it.

Wow , I wish I had known about these wrenches a long time ago .

Doesn't work as well as I thought it would for the price. But I haven't used it much yet. So with more using it, might get get better with it.

This Wera spanner is an incredibly practical and high-quality addition to my tools. The self-adjusting mechanism works flawlessly and practically replaces the need to carry a whole set of different sized wrenches. The grip on the bolts is very secure without damaging their edges. The build quality is solid, and the tool performs excellently for both fine home plumbing repairs and car maintenance. The investment in this tool is worth every penny. I am very satisfied!

I got it for my tools bag as everyone needs one of them. Super useful and versatile tools. I recommend it for tools lovers
