Purchased two Ultra Duo 80 Plus chargers from Tower Hobbies at a discounted price. The charger works great, completely as expected. Comparable to other similar spec'ed chargers on the market, this unit seem to be the best overall value. I have only one small issue and that is with the packaging. On one of the two chargers, the paint on the silver face plate rubbed on the inside of the box and wore off. This happens because of no foam or bubble wrap around the top of the charger. Other than that minor detail, I highly recommend this charger. *Software version 1.07 is available (came from factory with 1.02), not sure what changes come with 1.07, but downloaded the update utility from Graupner and installed it anyway.
