The Charger is great, but the program to run it is a bit iffy. And the documentation is not all that strong. It is a bit clumsy so have to load each program for each channel and not be able to save it. You must then store it to the charger. But if the chemistry of the battery changes, then you must reenter the program for that channel. It is fine if you are doing the same chemistry time after time for every battery. But I have Li Ion and NMH battteries, so I must change the program.
It has 4 channels and the programs for the channels can be a bit confusing. The window displaying does not expand, but I have overcome this with using the magnifying effect on the screen to fix it.
I took one star off from the review because of the software.
And it would be great if they had a cheat sheet what to set everything to for the different chemistries, but you have to look this up on the internet and make your own cheat sheet.
I have compared the results with the Xtar Dragon and they are pretty close to what they do, with the Xtar being more automatic. The capacity always almost seems to come out very close to each other. I must admit the other Xtars do not and do not charge as good as the Dragon. For instance, when I charge with their 8 slot or the Vp4, and then put them into the Dragon they show about 60 to 80% Charge and then charge up to the full capacity. I use the other two for just bringing the charge up so it does not take as long in the Dragon or the SkyRC.
This would be a 6 star review if they updated the software and put some capability to store programs that you could just recall from the software.
