6004 Joker XS Joker with Flexible Size Adjustment; 7-10mm

Works well for small bolts. Built well and seems to handle pretty decently

To my fellow AMTs wondering if this gimmick actually works and is worth the 30 bucks because you've never seen anyone using it: yes, this is the real deal.

This isn’t a joker….it’s a joke. First off, I thought when I bought this that it was the bigger version. It was a lightning deal at $33 so I bought it. When it arrived, it was TINY. I was skeptical because the tool clamps down on a nut or bolt head during rotation. To me, that seems overly complex. The range is slightly over 3mm so if you think about it, it’s not convenient. I roll a tool cart with all of my smaller wrenches and usually land the right one the first time. I don’t need a self adjusting wrench this small and you shouldn’t either. It’s existence is pointless. But that is besides the fact that it broke on the first bolt it touched. My instincts were right: I was removing a bolt from a lightweight strut cartridge on the hood of an Acura. At first, it had a solid grip as the bolt head was square in the jaws. I applied pressure and *piiiingg*…something flew out of the tool as it released the bolt head under slight pressure from my right hand. Luckily I knew to press open handed as to not jamb my fist into sheet metal and the strut assembly. Wow. I was left with this joke(r), dangling it’s now broken head in a loose manner. I could only speculate that it was a spring of some kind but it was so small, I never found it. For the $ I paid for this tool, I was not happy. I got my torque wrench out, set it on inch pounds and loaded the bolt head with 20 INLB before it gave. Unbelievable. I immediately went to my orders page on Amazon but wouldn’t you know it: I missed my return window by 3 days. That’s because the tool is so useless that it sat in the tool chest for the opportunity to use it. FAIL Hence my negative review. I did not apply the tool in the wrong direction, either. I was within range of the marking on the tool which is also a mystery: 7 1/4 to 10 3/8. Is that metric or imperial? It appears to be both which makes no sense to me. Wera, if you are reading this: I’m never buying one of your tools again. If I see your tools in a buddys tool kit, I’m going to laugh at him and tell him he bought junk. Because that is what this wrench is…Junk.

I did not order the correct size but it is the best tool you can have for those small, nearly anatomical impossible placement of a connection. If your young and like to spend more time on the floor to install plumbing, keep doing it the hard way. This is a time and back saver.

Cost too much for what it is, quality is good

stupid-expensive, worth every penny.

I haven’t got to use the wrench to it’s full capacity. So far I’ve only used it to loosen small bolts that connect capacitors to inducer motors. It tends to slip, however to be fair the screws are in a very awkward position. I’ve been investing in more wera tools and these are really cool. I plan to get the entire set soon.

I bought the whole set of them and I still have them but have other tools that do a way more affective job.

7mm 8mm and 10mm are what I usually have to carry, now just the one small tool with the ability to use it like a ratchet. Works great!

Igual podrías imaginarlo mas grande, pero el tamaño es fenomenal y su uso y practicidad FUERA DE SERIE.

Quite small for the bigger task but the right size and weight for an EDC set.

Great self adjusting wrench, so much better than the old style screw adjustment although the range is much small with these - the XS is 1/4 to 3/8.

Ho acquistato questa chiave un po' per curiosità e devo dire che mi ha davvero sorpreso. È molto carina e compatta, perfetta da portare sempre con sé o da usare in spazi ristretti. Ma soprattutto è maneggevole e comoda, il che rende il lavoro molto più piacevole. Stringere le viti diventa un'operazione semplice e veloce, anche quando si ha a che fare con viti dure o incastrate. Una delle cose che ho apprezzato di più è il fatto che, grazie ai bordi stondati, la chiave non fa male alle mani nemmeno quando bisogna esercitare più forza. Un dettaglio piccolo, ma che fa la differenza quando la usi spesso. In definitiva, è uno di quegli attrezzi che sembrano un gadget, ma poi ti accorgi che è studiato benissimo e pensato per chi lavora sul serio.
