I was recommended to try this by a friend in Spain, Great idea and works well with my Samsung Galaxy S4 - love the fact you can purchase additional tops for the Gym and integrates my Heart Rate Monitor.
Fit was a bit small but overall product is great. I am a small in everything but this was a bit of a tight fit so you may need to go up a size. It is hand wash only but given the technology I would imagine all makes and models are. Went back to purchase another immediately after receiving it and found that price had been put up from £12.99 to a whopping £49! Have found cheaper versions from other stores so won't be buying again at that price and it receives only 3 stars from me as a result. I do wish sellers would be more transparent with their pricing. If you're reading this do not bother buying this at this price.
