> 24 hourI bought these to replace some other DRV8825s I purchased off of eBay that would miss steps. These work great and are relatively quiet. Im using these on a RAMPS 1.4 board with an Arduino MEGA 2560.

> 24 hourIve used 1 out of the 5 drivers so far without any issues. Initially my order was shorted 1 item out of the 5. I contacted the seller and they sent out the missing piece. Overall I would buy from the seller again.

> 24 hourThese work just fine. Remember to adjust the screw for what you need. If running for a long time keep a fan blowing on them or keep a few spares on hand.

> 24 hourExcellent product. Was shocked to find out it supports 1/32 stepping. As always, very your voltage before attaching your steppers. Mine were all around 0.6V except one that was at 2+V which could have fried my motor.
