I was quite happy with this vise for the first 3 or 4 years. Then the eccentric nut began to slip when attempting to loosen the vise. Not sure if it's actually a nut, maybe the vise has some play that allows the nut to click making it difficult to loosen the grip on the vise. I've tried to troubleshoot the issue but nothing I've tried seems to help. Now that the vise is about 5 years old, they are practically unusable. I give 2 stars because it worked great for a while. Just don't expect thisβ¦
