Routine maintenance checkup! No problem. If you live in the NYC you can drop your MYT Glide off . Within 48 to 72 hours, we'll give it back to you all checked out and given a clean bill of health. Otherwise, you can ship it to us and we'll do the same. There is no charge for this service. If a part needs to be replaced or upgraded, we contact you to discuss. It is that simple. However, you must contact us first so we can schedule a time.
