Purchased replacement of a second drill hammer other brands (HS hammers after a few uses, perhaps a bit too intensive !!!). I chose this product here based on the relatively positive opinion of many people who bought this product .. Although a little heavy, it suits me perfectly to hammer holes and small demolitions. I used it for masonry demolition work for 3 hours batch (periods 7to 8 min). No particular problem. As with any amateur material that makes us good service, it should not be too warm to keep the hammer this time. Think back fat regularly and verify that there are enough at least before each new use. Product supplied with spare coals. Given the price and the number of times this hammer will serve me, it comes to me less than a rental and more I immediately at hand (this was true for my previous hammers, but celui- seems stronger to me)
