I shoot the Burris too. This is the third year I have used it. I started out with one of the cheap ones like you have found at Wal-Mart, mine was a Simmons. When I put the Simmons on and patterned my shotgun parts literally started falling off after about 8 or 10 shots. I was shooting normal 3" loads at the time. I sent it back and bought the Burris. I haven' t had any problems with it. I change the battery one time during the season, not because it has gone dead, just because I want to make sure it stays lit. I really like the red dot style scope, but like PA BeardBuster said, it is better if there is some kind of mounting system already on your gun, either it is drilled and tapped or, like my Xtrema, dovetailed to accept a mount. I used a saddle type mount on my Pintail and I didn' t like it much.
