Good looking strap

I like the strap. It fits the watch (Seiko 5 6119-6023) perfectly, and looks good. I will definitely consider purchasing more items from this website.

No more sore skin

The band that came with my Fitbit irritated my skin so I thought I’d try this metallic option. I’ve had it over a month now and no more sore skin. Very happy 😊

Pretty

I brought an Apple Watch as soon as I found out I could wear it as a fob watch for work, as I am able to wear a watch. To protect my new investment I ordered this super cute case protector as I know I am going knock my watch around at work with it hanging on my shirt.
No broken watch for me!!!

Much more comfy than the original Fitbit strap

I was getting a rash from prolonged wear of the original silicone based Fitbit strap. This one from Strapify is a lot more skin friendly, but my skin does still get a bit irritated if I wear it too long so I might purchase a new strap (likely from Strapify) which uses a different strap material.
