2 of 4 not working...bad batch? Wish i bought something else though at this point
Finally got around to do doing a build with my son and w of the 4 escs were defective. Wouldnt read through blheli and one even burned through the plastic cover. After building nearly 100 quads i would have to say these are pretty much at the bottom of my list. Dont waste your money on these for sure. Unless i somehow got a bad batch or something?

Good woorking esc's
Good esc's! I'm currently using them on 2 quads and I bought 2 more sets for spares. Dshot requires no calibration in betaflight and all modes work as they should. Would buy again!

DO NOT BUY
Bought these to replace an ESC that went bad on my eachine wizard. Says they are rated for 20A just like the ones on the eachine, but for some reason I've burnt through 3 out of the 4. I wouldn't waste your time with these because clearly they aren't made to handle 20A.
