I have a purple harbinger and found this as an option. It was super cheap but the reviews were great so I took it. The packaging was simple and efficient. It comes with tools that can be easily installed. The product is good for the price. The only issue, which through my fault I didn't notice, was that the purple color I received really contrasted with the original Garmin watch. This made it look very cheap. I contacted customer service to inquire about the return policy so I could get either the black or white option. We heard it straight away. They give a free additional group for a submitted review. That makes it 5 stars as I don't have to return the old one etc. Otherwise I would give it 4 stars as it would be a hassle but honestly it's not their fault. I'll see how long it takes before I get a new group. I don't like feeling bribed for a review but for the price this is a good product. Slightly inferior to the original, but again relative to the price.
