So far so good! I've had a few pots worth of tea from my triniTEA and haven't been disappointed at all.
So, here is some info for those who were unlucky enough to order late, or may still be deciding:
There are 3 controls on the unit, as pictured on the site, but what you can't see in the picture is what those controls do. One is the obligatory on/off switch. One is the temperature switch which reads I and II. I is warm (180 probably, though I haven't measured to see how accurate it is) and II is hot (boiling). The third control is a dial which lets you select the steeping time. It's analog and lets you select anywhere between 2 and 7 minutes. I timed it on 2 and 5 minutes and it seems to be accurate. Since it's analog it should allow for those who prefer 3 1/2 minutes for this tea, 5 3/4 for that tea, etc. I generally stick to 3, 5, and 7 but it's nice that it's flexible.
The controls are pretty simple and using the unit is a breeze. There are a few things I wouldn't mind being changed in another version of this, if that were ever to happen. None of these are deal-breakers. This is a very nice tea maker. I'll start with the more important things and work my way to "would be nice."
1. More control over the temperature. Not everyone steeps their tea at either 180 F or 212 F. For most teas, these are OK, but it would be nice to make this more variable.
2. Digital readout and entry for the steeping timer. I would like to know how much time is left while it's steeping. Also, even though the timing dial is pretty accurate, I'd rather enter time digitally (more like a microwave, less like an egg timer).
3. Make the infuser a bit larger. When making a tea that tends to expand a lot, the infuser seems a little small for the volume to which the tea wants to expand. The tea still has room, but it's more constrictive than something like the ingenuiTEA. I tend to make my tea a little strong, so other people may not experience this.
4. Make the beeping less annoying. Maybe it's me, but the beeping that lets you know when the triniTEA is about to do something or that your tea is ready, is a little to loud and annoying. It could just be me, though.
The only other thing, and it is probably just my unit, is that as soon as I put water in the reservoir, it slowly starts dripping into the steeping chamber. This happens even if the unit is off. It's only about a drop every two or three second, but I'd be willing to bet that it's not supposed to do that. Probably a bad valve or something. I'm not really worried, because by the time the water is ready, barely enough water has dripped down to cover the bottom of the steeping chamber, so this won't really affect my tea. The steeping chamber does not seem to have this problem (it doesn't drip into the carafe early).
Anyways, sorry for the long post. I'm really loving this tea maker and I hope you find this info helpful.
