TEVO unreliable products.

I bought a hand-held mini vacuum cleaner from tevo. from day one it did not perform properly and was sent back for repairs. shortly after it came back it started giving trouble again and I had to send it back again for repairs. a guy called me and apologized and told me there was a problem with the batteries. when it came back the thing worked relatively well, but after several months it started giving trouble again, is suspected it was another problem with the power. that was the reason it was sent back for the third time. now a Tevo employee called me ta say that the repair would cost 250R +.....because it is out of warranty. my advice is don't buy stuff that risks to break down a lot. leave Tevo stuff on the shelf.
