Well built and light device. It is confortable to wear without a counterweight.
The lenses that come with the case are good, with no noticeable distorsion and acceptable eye relief distancie, but the exit pupil is too small and the image will get blurry if not perfectly aligned with your eye.
Not sure if the IIT is a gen2+, no datasheet is provided. SNR is low compared with other tubes seen on internet and halo is notorious, however this tube performes ok in most scenarios and no blems can be seen.
All in all I'm happy with this product.
