Yes I have one, just got in hand on the 5th. I have been experimenting with various heights above ground level and comparing to reference (Vaisala) instruments.
It has its pros and cons and the amount of stations that are online is quite impressive. However, with data collection one must consider all the variables in various locations and the skill/training of the owner. I suppose with the sheer number of stations the bad eggs can be sorted out. The price point is attractive and the mount/appearance is appealing to most novices, etc.
