I'm an average sized guy and found my old seat so incredibly painful it was almost unbearable. Since buying this i can now ride for hours without even a hint of soreness. It's never going to win any prizes for looking great as it's quite large but that was the least of my concerns. If you get a sore bottom from riding then definitely buy this.
This is far better than i expected. It's big enough to house a few essential tools and holds my iPhone perfectly. It enables me to control the iPhone easily whilst in the case and run cycling apps whilst riding. I was sceptical how goodd this would be but it surpassed my expectations.
