I bought a jackhammer from Mytopia a month ago, it was supposed to be a German design, it worked ok, but leaked grease like a seive. Made in PRC, the manual was unreadable and all in all it was one shoddy piece of equipment. It has since been returned to them at their own cost. I am not saying that all the gear from them is shoddy, just my experience. I have yet to receive a reply as to what they are doing, they have had it for 10 days now.
