When changing wheels mounted "snow tires" with mounted wheels "summer tires" (and vis versa) to a garage that has not supplied the tires of your vehicle, it can cost from 15 to 20. From this observation and having 3 family cars to "change" every 6 months, I began to perform the operation myself. But we must recognize that perform this work with the basic tools of the vehicle is quite tedious. This is why I started to equip myself a little, and he was missing more than a screwdriver pneumatic called me "impact wrench". In my local DIY store, impact wrenches "very ordinary" is sold only 80. A ride at Amazon, and I realize that for the same price, I can have a cabinet, whose tools perfectly complement (without duplicates) bought the box with my compressor, with many opportunities offered by the presence many accessories and various tips. Moreover, it seems that Mannesmann has a pretty solid reputation, hence, the decision to purchase. Concerning the processing of the order, the delay, delivery and packaging, everything was perfect. The box was well packed in a thick Amazon card for the last stretch of the transportation provided by the Post Office. At the opening, there was a second very thick cardboard that had served the international transport. On the carton containing the names of great French port. I think the product was manufactured in China, like many other tools now, even for big brands. It's not easy to find the traceability of the production of this product in this documentation, but it does not matter compared to my need. Finally after we discovered the cardboard box with his third (late) with product images and diverse information. After removal from the cardboard, plastic packaging was in perfect condition, as well as machinery and accessories, even if some bits left their original location. A quick read of the manual shows that there must be a few minutes to activate the tools to assemble the particular air intake fittings supplied in the box, and check the oiling of equipment in need. Note that, assembled with their fittings, tools no longer fit into the box, it's a shame. I tested the real impact wrench sizes and works perfectly well for screwing and unscrewing. Still hard to imagine the life of the tool, but the beginning is promising. The ratchet screwdriver is also very practical with its wide range of sockets of various sizes. And just to see if they worked, I tested the other two machine (chisel hammer and grinder) and I did not detect any anomaly. I am satisfied with my purchase and its good quality / price ratio.
