I did a ridiculously obsessive amount of research when I wanted a robot and it came down to either the Y&T 989E/A9 or the B3 plus a catch net. Ended up with the A9 but frankly the latter probably would've sufficed since I didn't end up using it much.
The B3 is about half that price in china which compares favorable to the Newgy on value. It has the benefit of 2 wheel + IR remote. It cost less than some fancy blades or ~two Tenergies so a no-brainer if you have a table at home or take it to the club for warmup.
The only review on the internet on some chinese forum seems favorable.
