Snuffy789 I have been using Leupold optics for over 30 years and still use the first Leupold optics I ever bought and they are still as crisp and water proof as the day I bought them. And customer service is unmatched by anyone else hwo sells top quality glass. I once accidentally ran over a pair of binoculars and sent them into Leupold for an estimate for repair if it was possible, they were pretty bad off. A couple of weeks later I got them back in the mail without any sharge for shipping or repair. they had to replace the glass and a tube too. I also dropped a rilfe off the Mogion Rim and it destroyed the scope, a Leupold 3x9x40.Again I sent them in for an estimate and got them back at no charge for a brand new one. They don't care what the cause of damage was, they just fix it or replace it at no charge. I worked in the retail business for a while and remember a couple of simular Leupold optics being severely damaged and Leupold treated them the same way I was, no questions asked.
But also of most imprtance is the quality of their optics. They make everything in a quality that is as good or better than glass costing thousands! My first rifle scope from Leupold was a decision I made because my Wife and I both ended up with stitches and concussions resulting from poor eye relief, something you'll not have to worry about with even the least expensive Leupold scope. I wouldn't hesitate to use their inexpensive 3x9x40 $250 scope on any of my high powered rilfes and I do. They are crisp, hold their zero no amtter what caliber rifle they are on, don't fog up, are gas pressurized to endure any water element above or below surface, and you can clean them by washing them under soapy water without worry of leaking. I could go on and on about the outstanding quality of Leupold, but the real test is buying Leupold and discovering for yourself the unmatched standard of quality of their optics, regardless of the price range.
Each year Leupold replaces my eye cups for all of my glasses and has also replaced turret caps when I manage to lose them. And as usual, all it takes is for me to send and e-mail asking them to sell me the replacements, and I never get a bill, just the replacemnts needed, even for my old and out dated optics.
Also, all of the current scope come with a threaded objective lens for the light filters they make for them.
