Bests & Worsts Reviews from Amazon

Stopped working after 1.5 months. It works for 60 seconds then stops. This is my 4th maytronic in 5 months. Out of 30 day window. Waste of money. --- UPDATE --- I am an engineer, so since it was out of date for return, opened it all up, opened the top carcass, when I was going to unscrew the impeller, I got quite a strong electric shock (not sure if this is safe?). I opened and realised the circuit board tested the wheel motor and the servo correctly but it seemed to fail on the impeller and the light started blinking after that. I decided to open the impeller motor, and there was the bug. The small copper cable that holds the graphite contact was stuck behind the graphite holders in contact with the metal carcass of the motor (I guess the electric shock came from there. This was undoubtedly a factory defect. After placing the cable correctly from the top of the graphite holder, returning the inside plastic to proper isolate the electricity and reclosing the motor it worked again like charm. It took about two hours to fix. After opening and spending a couple hours analysing the components, I can confirm my above statement that these things are cheaply built and lacking proper quality control. 1) I am not sure I would trust to swim at the same time as this is working. 2) If you buy, try it extensively within the first month as it might fail, and no repair shop would do the type of repair I had to do. 3) Recommended for engineers that like the challenges of unreliable equipment.
