5 years ago I purchased a 24mm ES68. I have 2 that I binoview with. Recently it started to develop a little rattle sound if I shook it. The eye and field lenses were firmly in place so not those. I suspected an internal retaining ring might have loosened. I would have fixed it myself except that this eyepiece is Argon purged so did not want to struggle with that. So I sent an email to Explore Scientific Support and asked them if I can return it for repair. The quickly sent me an "RMA" number and image to print and put on the package. I paid the shipping to get it to them. Today I got my eyepiece returned and repaired and at no cost (other than the postage to send to them)! No other questioning between me sending it to them and them repairing and returning. This is how warranty service should be!!
Kudos to Explore Scientific!!
