Review on GemRed Aluminium Digital Angle Finder by Kyle Kriglstein

This angled viewfinder seems to work well but I can't give it 5 stars. I ordered the product on Friday and it arrived on Saturday. I tested it immediately and was surprised that there was no battery in the box. I turned it on and the display was blank. I opened the battery compartment and there was already a battery in there. I changed the battery and the angle finder didn't work - either all 8s or all zeros or nothing at all. I agreed to return to Revain on Saturday evening. On Sunday I got a second angle finder. The battery was packed separately. I installed the battery and it worked fine. I'm happy with that. This is a good angle finder. Apparently I received a defective item that was already returned by someone else. I was tempted to give the item 3 stars because of the aggravation. However, I'm giving 4 stars based on the fact that I received the new angle finder within 1 day and it's fine. It was also relatively easy to return the original angle finder to Revain. I suggest testing such an item as soon as you receive it. So many reviews of similar products say they waited too long and couldn't return the goods.
