You can't get any cheaper than this. I have one, use it occasionaly and it works fine for 4.8 or 6.0 volts. Contary to popular believe I fast charge all my nicads and nihm's without any issues. I was told by NOBS batteries where I bought my last battery packs that they'll last longer fast charged than slow charged - go figure.
