I already had the Black Shark 3 and 4 fans, I was super happy with them. I 've also ordered this one because you save the clamp method by metal bases. I 'd say it cools a little more than previous fans, even though it has fewer blades, I imagine they 've optimised the air flow in some other way. My only hit is that it has no power and off button, as they did have earlier, and that the USB-C cable it brings is USB-C on both sides, when above (and logical) it's that it was USB-A to USB-C, because with the power of the mobile it's likely that the fan won't even work. It also has to be noted that it only brings a metal base with sticker, if you want to use it on other devices it touches to buy more bases. Obviously I don't recommend officers, who cost a paste to be a metal bucket with glue. On Adafar you have 8 sheet metal packs per 2 €, which work perfectly, although the glue is not so durable.

Great cooler. Good magnets. Works offline without applications. Fan rpm varies depending on the cooling temperature of the contact pad. At first I thought that he was spinning at constant speed. In the kit there is a metal sticker. Executed soundly. Thick enough metal and not thin plate. For this special thank you for not saving on small things.

Took for cooling Red Magic 6S pro. the cooler copes with its task perfectly, but the pads are held very badly because of the rounded body of the smartphone... You need to catch the place of the sticker lining.

Very nice and practical. A shame not have button or lever to off and on. Version 3 has a larger cooling area but is stuck to a clip preventing so put a iPad for example only cell.

Excellent product, expected only come with more stickers can be used later on other devices, included only a. Meets function perfectly, recommend the product Special for iPhone!
