Not great. Doesn't actually fit the instinct properly.

excellent value, quick service, very comfortable
Exactly what it said on the box!

The velcro in this is strong! Very sturdy and although possibly a little bulkier than it needs to be, a great strap. Easy to put on with one hand.- From Amazon.

I have not been happy with the silicone strap that came with my Instinct 2 and was looking for a good quality velcro strap. This is the one ! I like everything about it, it is easy to fit using the 'quick fit' and once on not only is it very comfortable but it also improves the look of the watch. The strap is sturdy with strong velcro attachment and in use I do not think it will open or come off by accident, even when active while working or doing a sporting activity. I think £19.99 is good value, you get what you pay for, and I recommend it.
Update: 4 months later, this is the best strap I have had for my Instinct 2. I do a lot of outdoor activities and this has held up through everything. Fantastic !- From Amazon.

Exceeded my expectations. I purchased this for the Garmin Solar 2S because i didnt like the $5 kids watch band it came with. Man let me tell you. Having the watch with the white face, and black accent it was difficult to find a band that would match well. the white and black cammo band looks fantastic. It makes the watch look much more rugged, and the greatest benefit is when working on the computer, there's no metal band to rub against; scratching the lap top or desk. Its a comfortable fit, and was very easy to install. It doesnt come with pins however so youll have to remove the OEM pins and insert them into the band. All and all though i'd highly recommend. Looks great. Very comfortable. Easy to install. Feels very durable. Well worth the price.- From Amazon.
