Query: DO NOT BUY THIS PRODUCT

I bought one, which worked for about 20 hours, and then broke. They sent me a new one after HOURS on the phone with customer service, which is SO TERRIBLE I CAN'T EVEN BEGIN TO DESCRIBE IT. And the new one they sent me (not "new" but clearly refurbished) was BROKEN. I am so fed up I am just going to take it as a loss and go to Garmin. It may be fine if it works, but it breaks all the time and the company is an absolute nightmare to work with.
