As such, the device is not bad and useful for occasional use but expensive. For me, the first device was 2 weeks (1-2h / d) in use after klempte one of 4 pips, which the function has been greatly affected. So unit back and get a replacement, this stopped right turn about 2 weeks and then the same defect. Exchange problems and a third in his hand. This time the plastic is broken down after only one day use, so the test was failed. I now need even to tell no one that I would use this thing wrong, it was so Dandelion and purposes removed, especially the latter have nasty solid Fahl roots, which the unit has been operational long, were super removed. There can be only one star, because of its durability (PS: 0 stars he will not accept).
