I used it few months and it is very nice device. I replaced it with PRO version and in my opinion the difference is huge. I can give 4 stars for UTCOMP-3 and 5 stars for UTCOMP-PRO. First of all - number of inputs - I can connect more sensors to pro version (the reason why I changed). Secondly - OLED display - it is gorgeous. Black is black and contrast is phenomenal. OLED from pro version is also noticeable bigger and has prettier icons. There is more differences but I mention from my point of view. So if you do not need to connect a lot of sensors, LCD display is fine for you and you do not need these extra features than basic version is good choice.
