The device is not small, it fits so well the whole hand in, not only the fingers, so you need a bit place for it. The palmrest is also mirrored and can be taken out, which is a good idea, because they can be so quickly and easily cleaned. The fan is clearly audible during operation, but not as loud as a hair dryer.
Up to this point 5 star, now the only sticking point is: who bears no gel nails and works only with normal nail polish, which can dispense with this device. Normal nail polish dries not a bit faster than usual! With Fan eg drying takes a "Rimmel London 60 seconds" nail polish more than 4 minutes, which is endtäuschend. Connecting it to the UV lamps will have no effect on normal nail polish.
Conclusion: Good tool, but easy to handle only very specific use. Anyone working with gel nails will surely be satisfied, who uses only nail polish can keep their hands off, so 1 star deduction.
