Sounds like they are a lot better than Winter. I had two of their
altimiters requiring repair, one under warranty. Sent three emails to
address on their web page requesting instructions. They never once
responded.

Wings & Wheels had a package going to them and added my items to the
package. It only took about a month and there was no charge for the
warranty. I had not even purchased the altimiters from W&W. Good
service from them. Where was Winter?
