I wouldn't consider the Jebao as having a good record, way too many failures in far too short of time.
Comparing it to a Vortech is silly, apples and oranges. I never really understand why people do that? Maybe because they will look silly comparing to a Tunze? Compare it to a Tunze, which is what the Jebao was copied from. When you do that, the Jebao looks like what it is, a cheap knock off product. There are many of us with Tunzes over 10 years old, and some with over 15 year old Tunzes. I highly doubt any Jebao will make it to the three year mark. Junk is junk, hype is hype. Quality stands the test of time and bottom tier Chinese knockoffs never stand the test of time. You can buy better quality Chinese products, but they do not have Jebao written on them.
If people are happy with low priced, low quality items that fail in a short time or have to constantly clean them to keep them going, then maybe their priorities are off. Spending a little more to get something that lasts is always a better use of money.
