The feature I like best is the rimless lens. I have always been annoyed with the large rims around the lens on most magnifiers. This lens is decent quality. It gives little distortion and is very clear. It is only a 1.5X magnifier so if you need more look elsewhere. For me the 1.5X is just about right.
If you are looking for a magnifying glass for your saw or just general use in the shop this might be a decent choice. Your not spending a large amount of money so don't expect commercial quality here.
I could not find the tool on the Workshop Tools website so I went searching on-line and found it on Amazon. The Amazon price was $5 more than at Workshop Tools but that's still a decent price. Here is the link to the tool on Amazon.
You may be able to call Workshop Tools at the number on their website and order the tool but I did not try that personally.
Here is a link on Amazon for the same magnifier with 2X magnification. It is listed at $12. I suspect it's the same tool just listed with different specs. That's pretty common on Amazon from different sellers. It's funny but the seller for this one on Amazon is Workshop Tools.
