I received my rotary tool without some accessories, the key and the wrench so I couldn't assemble and use it.
Contacted service center, that was easy. Then it was for few weeks exchanging messages and photos before they agreed that it was their mistake! They tried to push their mistake on anyone: postage people, me and that "listing doesn't include these accessories"!
After a month of a purchase, I finally got a package with accessories! And what a surprise, they didn't post the wrench! Without it you cannot assemble the rotary tool! So disappointing!
Don't buy, unless you have a lot of time to deal with them!
