AVOID AT ALL COSTS!!!
I went to see them to have my shock absorber cartridge tightened. They did it, but the following week the same thing happened again: my cartridge came loose (a known problem with this shock). So I went back and asked them to tighten my shock with a strap wrench. The mechanic told me it absolutely had to be removed from the bike to tighten it, to which I replied that no, his colleague had done it the week before without removing it. He argued with me and decided to remove it anyway. One of the screws was supposedly seized, so he stripped the screw head and tried to reshape it with a Torx socket, but he never succeeded. Meanwhile, his colleague came over to my bike and fiddled with my derailleur adjustment. I explained clearly and politely that I wasn't there for that (I'd been waiting for almost an hour!). After a while, he realized it was possible to tighten it without removing it from the bike! He suggested using Loctite, to which I agreed. He then started unscrewing the cartridge on the bike. He had forgotten to deflate the tire; you can imagine the explosion that produced. He finally tightened it and gave me back my bike. When it came time to pay, he charged me for a derailleur adjustment I hadn't requested, and for the time he spent on it (I hadn't asked for a derailleur adjustment at all!). And on top of that, the derailleur was even worse adjusted than before! At the same time, I went back to see him to ask him to find me a screw, but he refused. I had to order one from the manufacturer, which cost me an extra €60! Dishonest mechanic and shoddy workmanship. I absolutely do not recommend this repairman!
(And by the way, it took me 30 seconds to remove that screw cleanly, lying on the floor at night with a Torx wrench and a hammer!!!)
