I had a Nitecore I2 that died on me early this year after at least three years of pretty heavy use. Those sleds were awful but yeah, it worked well until it didn't.That's smart thinking.. i already have a 2 bay, i'll be sure not to get rid of it. Some where in the attic i have a nitecore 4bay.. but yeah.. that's from two house moves ago. no telling what box that one is in. i thought it was crunchy anyway, and it only had lights.. no digital reading. but it worked.
