I am selling this item because I purchased it as a spare. It's an excellent product despite its low price. It's waterproof and durable, and the battery lasts about two and a half days with always-on display enabled. If you turn off the always-on display, I think it will last the advertised 7-8 days. The display is very vivid and beautiful.
