THIS tidy package is simple and attaches tool-free to most seatpins, but is happiest on a conventional round one. We love the fact this is a rechargeable light, which is quite rare for a rear light, even better that it's via a USB port (makes charging lights at work a bit easier then the usual hunting for a spare socket under the desk). The Rapid 1 had no problems in the wet conditions....and did put out a fair amount of light for such a small unit.
