Replaced ESCs were perfect
Received 4 ESCs and upon testing, found 3 with defective waveforms. Returned order to Amazon. Replacement was ordered promptly by Amazon and received within a few days in Fiji. All ESCs showed perfect waveforms. Very happy :)

All 4 seem to work. I will update when I have some time on them
They look to be well made and for the price for opto speed controllers, I thought I would give them a shot. I will update after I have some flights on them.

Wires are too short
I'm using s500 frame and the wires can't reach the pdb

Inconvenient startup, but works fine
Inconvenient startup procedure, but the ESCs themselves seem to work fine for my 2-3s setups

Look to be very nice quality
These are nice quality 30A opto ESC's. Comes with some instructions. Has the three bullet type connectors to connect to the motors. Overall, very nice.
