Looks nice.
However, after only a few weeks, one of the two small screws that attach the motor to the unit became unscrewed, causing the whole device to fall to the ground; as the blades were rotating at quite a speed. Once the screw had been refitted, and the other screw tightened, the blades now rotate off centre, the whole thing now moves slightly around the top of the log burner!! 
The screws have no method to prevent themselves coming loose, and the threaded portion on the housing needs to be fully enclosed, and not the silly design where the threaded part on the unit is a slot; so not a fully enclosed thread. The mounting screws need to be longer, with a better method of ensuring that the screws cannot become loose/fall out; and the screws made to go into a fully threaded part of the unit; and not into a slotted threaded 
Had the unit been used more than a few weeks, I might have given a 3 star score, but as it is; 2 stars is all I'm prepared to award.
