since it's a 50 mm objective lens with a 15 power you're going to be discouraged when there's low light situations(the best time to glass/find an animal). I have a pair of 15x60 that do really well and I actually use 12x50 cabela euros a little more than the 15's, they're just really really clear and bright. I saw some up here for sale a few days ago with an awesome price. The euros are dang near even to me to a pair of slc swarovskis. You can even read the reviews on them.
