- *****- Feedback left by buyer.Past monthVerified purchaseJust what the doctor ordered ! Works as it should. Box was a little damaged during shipping but product looks ok. I sent seller a message too see if he has the other main gear for sale but no response as of yet. Very happy with this purchase. Price was great but shipping was slow.
- 5***r (35)- Feedback left by buyer.Past yearVerified purchaseLooks Just as shown, bigger than I thought it would be, but it goes well with the size of my telescope. it came well packed in cut out foam, in a box, and in a bobble wrapped envelope. It was delivered fast. Excellent clarity. And it has a way to focus to meet your eye sight really nice. It's made well and worth the money. I would say this is a good company to do business with and I'm sure I will do more business with them. Thanks for your caring attention to my order.
