You will like the 4010Duo. I had the Hyperion SuperDuo right after they came out. I used it for a while but got tired of it's size. Thing was humongous. Like most dual channel chargers, the Hyperion seemed like they just shoved two separate chargers into one case. The Junsi 4010Duo seems like it was designed as a dual channel charger from the ground up. Also, it is way smaller than the Hyperion SuperDuo and smaller than the Hitec/SkyRC/Protek/etc 400w x 2 charger.

Few functional pluses of the 4010Duo over the SkyRC 400w x 2 charger:

- IR measurement as you said.
- Ability to see cell voltage when not charging.
- Being able to construct a power supply for the Junsi charger out of Ebay server power supplies. Hard to do this with the SkyRC chargers as they only take 18v max inout.
- 130w discharge capacility of the 4010Duo compared with 25w for the SkyRC 400w x 2.
- External discharge features of the Junsi chargers.
- Many more that I have not listed.

Now don't take this post the wrong way. The SkyRC charger is about the best bang for your buck charger you can get. Also, mine has been very reliable. The Junsi 4010Duo just gives you many more advanced features and capabilities over the SkyRC charger. Basically you gotta pay to play!
