Via Aqua chiller...good/bad?

[WarmWaterDiver]

Does anyone know anything about Via Aqua chillers? There are a few on ebay for a decent price but I can't find much about this brand. I'm afraid I will be taking the cheap way out and stuck with chiller that doesn't chill.

Ive never heard of those before.What kind of guarantee do they have?
