Looks built nice and very similar to the Eotech. Price is really cheap. For just target and basic fun needs, it will probably last long enough. If your betting your hide on it, your choice.
Eotechs are built very nice and even if similar in appearance, the internals are what is going to last you over time. Switches, battery life, adjustment precision are all things that seem to get lost when using less quality parts.
Still be fun though.
