The third device (two bought as a gift), ordered from this seller. First for 5 months. Still working. Of the minuses: I do not use those nozzles that have rubberized tips. They quickly peeled off and no miracle glue to hold them. It affects the frequency and force of impact. According to other parameters there are no complaints.

Delivery Device which promises, great quality, fast delivery, and the seller said the amount requested, and was not taxed, arrived in 9 days working capital SP
Powerful device, the lower level is strong, well packed!

Excellent product, very grateful to the seller I would rather say excellent seller I had already bought one but I believe it was factory detail since it did not work but the seller after almost four months of making my purchase very he offered to pay me $ 15us and make compensation for another product.

Thank you, everything is like in the description.

Very good quality, motor is very strong and quiet.
