Battery life is what killed the trace and tracer for me. Not a fan of flash so always had them on low constant - they'd be indicating amber after two commutes and would die half way through the fourth. Also didn't like the elastic protective band that covers the USB port - was fiddly and felt like it wouldn't last. I now have the Blaze, which is pricey for a rear light but lasts around two weeks on low.
