I have had no problems from this battery recharger in the 3 years i've had it. I have also saved a good amount of money since I recharge batteries for my xbox 360 wireless controller so much. I also recharge batteries for my tv remotes.
My Old Gameboy or Other Handheld Game Consoles
This Product would been very useful for a Gameboy I use to have as a kid because it went through batteries faster than anything I can recall. I did get the Gameboy when it first came out 20 years ago.
They probably have improved on the battery efficiency of the newer handheld consoles since then. If they haven't than heres a solution. Either way about it this would be good to save money as all the little costs add up more than some people think.
Ease of Use
Operating the Vanson Speedy Box is very simple. All you have to do is put the batteries in the recharge area and the indicator lights will remain red if not fully charged. The recharger indicator lights will turn green once the batteries are fully recharged.
The only complaint I have is its not a Solar Powered Battery Recharger as this would have been the ultimate in conserving energy and saving money. I couldn't afford a Solar Version at the time so I got this Battery Recharger instead. This is more convienient than a Solar Version though.
Battery Types You Can Recharge
You can recharge up 4 AA, AAA, C, and D batteries at once. 2 Slots are available to recharge 9 volt batteries. Its made to recharge Ni-Cd and Ni-MH type rechargeable batteries.
