The Compact 10 is an unassuming little number that simply does its job well and leaves without a fuss. Including a torx and an 8mm extension, it has everything you're likely to need out on the trail except for a chain tool.
It's properly robust, too: the plastic sides actually have a steel reinforcement underneath so it is a lot stronger than would first appear, and frankly we couldn't fault it for the money. It works, it's strong, and it costs £7.95. It wouldn't disgrace you or your bike.
