BAD QUALITY, August 28, 2006
This review is from: Vivitar 7 x 50 Binoculars (Sports)
Purchased because of very low price and 7x50 spec. I didn't expect great quality at this price, but did expect them to be useable. First one produced double vision. Took it back to Walgreens for another. The 2nd one has single vision but focus was so poor that I couldn't read a small distant sign that was absolutely clear with my other brand (low cost) 7x50.
Vivitar should be ashamed of themselves for selling such low grade trash. If you are tempted to buy these, go to a store where you can test a few and pick the best one.

Truly educational, but not in the way they intended, November 21, 2007
This review is from: Vivitar 7 x 50 Binoculars (Sports)
Oh man, these are trash. I picked up a pair at the local drugstore on a radical discount, just to see. They were so far out of alignment that even when I could get the images to merge, convex objects looked concave. Guaranteed to induce headaches. Then there's the mushy focusing, and the chromatic aberration on bright objects. Finally, the view is noticeably dimmer than in my 7x35s, which shouldn't happen with double the light-gathering area on the objective lenses (pi*35*35=3846 square mm; pi*50*50=7850 square mm). My guess is that the manufacturer should have passed on the "UV coating" and added some coatings to enhance light transmission, like you find on decent binoculars. If they'd done that, though, these would sell for more than the cost of a movie ticket (hint: don't pay any more than that for them!).
So I disassembled one side. Now I have a 7x50 monocular with all of the problems listed above except the misalignment, plus a cheap eyepiece for my travel telescope, two cool prisms to play with, and one lousy lens that I have no idea what to do with. So as a bag of parts to tinker with, this was a good buy *at the ridiculous discount I got*, but at anything more than that, or as a functional piece of optics that you can use for more than two minutes without getting a migraine, these should be avoided.

Poor Quality Control, September 23, 2005
This review is from: Vivitar 7 x 50 Binoculars (Sports)
I purchased and returned this product twice and then gave up and got a refund. In my opinion, either the product is defective or is packaged poorly. Both times the binoculars exhibited double vision. I was surprised that a Vivitar product would perform so poorly.
