What the differences are between the original ATK and ATK v2? I just watched the official video () and from what I can tell, they have new optical sensors and new PMUP.
The old optical sensors were prone to failing. Mine have gotten 'stuck' on several occasions, despite being clean. Unplugging them from the FMM was the only thing that would get them working again. I've read it is due to micro fractures in the plastic insulation, but I can't confirm that. Regardless, if they've redesigned the insulation to be more durable it would be an improvement.
I've never had an issue with my PMUP, but stories of PMUP failures are all over. A lot of these seemed to be related to the impeller, which makes me think they had issues with their supplier. Regardless, the PMUPs rating was something like 2.5/5 stars at BRS. According to the video, it has run-dry protection, thermal protection and protection from lodged obstructions. I'm guessing that all of these are the same (thermal protection.) It's very likely that many of the previous failures were caused by either debris or the magnet swelling causing the impeller to stick and that in turn causing the motor to over heat and fail, so a simple thermal fuse may go a long way towards making them more reliable.
Are there any other differences people are aware of?
