So far I like my Rattler TS25 very well. Have had it for a couple months with three coyotes to its credit. It is holding zero, haven’t had to touch adjustments since I first sighted it. However, since I hunt over bait and from a heated shack, that may not be a fair assessment since changing temps are what generally gets thermal. The scope is small, which I like and will double as a scanner too, and it has a good image. Controls are a bit different from my Pulsar Apex XQ38, but most scopes have some differences from another. Time will tell how well it holds up. Phone conversations with customer service have all been positive. I phoned to inquire about overall operation, not due to any problems, and to also make recommendations for improvement.
