Wasn't sure a cheap dual-slot would handle my mix of cells, but it charges my 26650 and 14500 at the same time without either one getting warm. The spring sliders hold the smaller 18350s snug too, which was my main worry.

Picked this up mainly for my 26650 cells and it handles them without a fuss, plus the 1.2V Ni-MH mode means my old AA rechargeables finally have a home. Both slots working independently is a nice touch.

Charged two 18650s at the same time and both were full in a couple hours, which is way faster than my old single-slot unit. The springy slots grip 26650s and little 14500s without any wobble, so it covers everything I own.
