It's not perfect but for the price of 20 euros this support is good; Positives: very handy one easily sets the desired height, the design is nice, there is a blue LED look great when the fan is running and this one is relatively quiet (you can hear but not annoying. the noise level is quite low). On the negative: it's all plastic and the latter is fragile. I got mine at the broken leg that holds the macbook so it does not slip. I preferred a dot of glue rather than asking the exchange. Then I do not find convenient to have placed the USB connector on the right. USB connections for the left and MacBook are delivered as USB cord is too short can not connect without using an additional USB extension cable. Another annoying little problem; the legs that prevent slipping macbook are high and do not allow to close its MacBook without moving. With regard to the delivery; nickel, fast, in short any worries.
