SinLoon Double Relay USB Watchdog Card Unattended Automatic Restart Blue Screen Crash Timer Reboot for 24H PC Gaming Server Mining Miner（USB）

Works perfectly when connected to miner motherboard to perform restart when the criteria has been met. Works perfectly with no issues. Has kept my miner running with a good preferred hash rate.

Works sometimes but it will have problems

Absolutely NO documentation included. There is a 4 pin header which needs polarity info for the power and reset connections. there is also a driver required to use for Windows 10. No link or any other info included. Save your money unless you want to spend 20 hours plus looking for documentation on a $10 board

Software sucks. Restarts randomly. Very unreliable, the software features don't work. When I induce a blue screen by pulling a pci card it doesn't restart. When the machine works perfectly it restarts randomly.

Save yourself some good time and get this cheap but super-useful USB watchdog for your server or miner. It will automatically reboot or reset if your computer freezed. Some setup is needed but worth the whole thing.Recommended...
