I have the Acuter ST22-67X100 zoom spotting scope angled, which has a larger objective lens than the 80. Overall very pleased with it and it does enhance my bird watching. Was disappointed with the zoom lens, fine at the lower magnification but blurred from 45x up. I purchased a fixed ME19 lens approx 30x and find this much better, also a wider view and all for 25 extra excellent.
Hoping to use with a digital camera, but no success yet.
I am sure if I used a more expensive scope I would see the difference but just starting out I find this better than good.
The bag is alright to carry it in but I always take it off completly to use.
