Hey mate. Should probably avoid double posting please. Yes, Optotronics are very high quality. If you want to do some research on them and see what other people have said about them, use the white search bar at the bottom of the page. There are plenty of results.
Yes they are a good company.
Just like everyone said, they are a great comp, and the owner is the one who gets back to you and il say within the hour. I dont know where your from but they deliver fast, around 3 days if your in the US
