Review on Meihejia Shank Degree Groove Router by Justin Butler

I wasn't expecting much from them since they're so cheap, but they actually work well. I used them for V threads and chamfers on a CNC router. The fir had a slight transverse crack, but this is not unusual for any part of the fir. I've also used them on cherry and ash with acceptable results. Can't comment on durability yet, but given the price I think they're fine for casual use.
