Swaros are good... Er.. Make that great scopes and Bino's.... However, Every manufacture is gonna have the occasional lemon, even Swaro... So, to think that swaros are perfect is a strecth.. In this instance, Swaro's customer service is whats gonna stand out.. Everyone is gonna make the occasional pos scope.. Its how the manufacture handels the pos that makes the difference... I believe leupy makes more pos scopes than anyone.. However, they also make more scopes than anyone as well.. Its the percentage of scopes that makes the difference.. I believe that Swaro and Leupy both have a small percentage of scope failures compared with the amount of scopes they build..
