I have only been useing Tasco's for 35 years but I have yet to have one that didn't work very well. I have had a few that the eye relief was a little fussy but most have been fine. NEVER HAD ONE BREAK. Paid less than 30.00 for most of them. They dont make them any more but the clearest toughest scope I ever owned (and there have been a lot) was the straight 6X tascoe world class. I probably sold 60 of them with nothing but praise. Since most of the scope builders have decided we want variables, it hard to find a decent straight power scope in anything over 4 power. I like my new Lueplds M8's and VX 1's but I have to many rifles to buy those for all of them. A Happy Problem
