I use both of these. Bought them after thinking I needed the highly praised Hyperion a few years ago, only to have it die within a few months of service with no one in the states to fix it. I began a quest to find a cheap, disposable alternative. If they break, throw them away and replace. I'm going on over 2 years now on each of these and haven't had any problems with them. I started with the AC/DC model for convenience (and seldom, if ever needing to charge over 1C). Then, the AC/DC version was only 150 watts. The newer version (link listed below) is now up to 200 watts. I bought the 180 watt DC version later with a cheap $40 power supply to charge at 10 amps (4S 6500mAh packs for eTruggy).

The balancing algorithm is one of the quickest I've seen in LiPo chargers. I race both eBuggy and eTruggy and have never had the problem of missing a race, waiting on a battery to charge.

Touch screen interface works well and is very intuitive.
