I think it's a great device to use and enjoy. Good optics, nice image for gen.1, very easy set up. And of course the booster lens - very convenient to swap magnifications, you do not need to buy two devices, you have two in one.
Ideal investment of your money!
Pros: Functional, good image
Cons: Looks a bit bulky with booster lens
