Things were like this, I bought a second puncher of this line for my company. one worked on the installation for a couple of years and there were no complaints. This copy lay in a case for about a year and waited for its turn. A couple of weeks ago we received an order for a large SCS and video surveillance, as part of this work, we have to drill a lot of holes for fasteners in the monolith. After working for a week with a frequency of 30 minutes of work, an hour for a break for cooling (because God forbid it is warming up), the barrel of the perforator fell apart in the hands of the installer along with the drilling cartridge (I will attach a photo a little later). Turning to the service center in Hong Kong, they explained to me that the guarantee for the stem part of the perforator does not apply. Although in this case I think that this is a marriage of a particular instance, tk. I repeat the second one works the same and there are no complaints about it. As a result, diagnostics are required for repair. maybe something else is faulty after a week of work, then 100% replacement of the element said 3500 for the material, apparently, I also have to pay for the work, and if something additionally failed, pay from above. So the vaunted 3-year Dewalt warranty is actually just a marketing ploy and does not apply to anything. Draw your own conclusions, I decided for myself that I won’t take Dewalt products anymore, PS 3 weeks ago, the charger from the screwdriver failed, under warranty for replacement, but also speaks of the quality of the products of this brand.
