The Optic Spacer: is NOT a completely universal part. The Optic Spacer is dependent on which optic you choose to use your adapter on. Each spacer has a range of sizes it can be used with, so you can use your spacer on more than one single optic!

The hotel was incorrect does not fit my spotting scope have emailed and tried to get in touch with the company about exchanging it or returning can not get a response back from them. There customer service in my opinion is terrible and would not recommend to anyone else.

Perfect digi/daily setup
So I have tried the competition and for my needs, the On Glass digi scoping system is the best and easiest setup with the most consistent operation hands down. Now, on top of that, it doesn’t interfere with the phone case I like to run. I use a magnetic phone case that I can stick on any magnetic surface and the On Glass adapter hasn’t I interfered with how I use it at all. Now, as far as the On Glass customer service…. I had the BEST experience with them. Let’s just say that there was an issue outside of their control but they still did more than a reasonable customer could ask for. They ship quickly and respond to questions even quicker. I recommend this product and company.
