1. GENERAL IMPRESSION.
First impression: HUUUUGE and SHINY :-)
High gloss coating + carbon + resin + LED strip around... a bit too much for me. But if you like such a "decoration" you can even say that it is elegant, it's just matter of taste.
Another thing you pay attention to is WEIGHT: 315 g with 21700 batteries. That's a lot but keeping in mind that the batteries themselves weigh 140 g it is quite ... GOOD result. Which doesn't change the fact that x217 is definitely not a mod to put in your pocket. So the general ergonomy is not bad, let's say: ordinary and quite SOLID.
Fire button has quite soft click but works 100/100, similar up/down buttons, maybe a little worse, because they work in some "plastic" way. Top and bottom:Top easily fits the 30 mm atomizer, the bottom hatch works well as long as we use standard batteries. When I tried to use a little oversized black Shockli 4550 I couldn't close it.
Finally a screen that is just RAZOR SHARP:
1.3 inches in TFT technology makes an impression, the character definition is PERFECT, without aliasing. The main setting is large, clear, while the other four indications are traditionally TOO LITTLE, especially since there is a lot of free space on the screen. Wasted place.
2. FEATURES.
* power: 217W (80 W in TC modes),
* resistance range: 0.1 - 3 ohm
* modes: VW, Temp, TCR, BYPASS, V, CURVE
* battery: 2 x 21700/20700/18650 (18650 with included adapters),
* weight (with battery): 315 g,
* dimensions: 92 x 50 x 33 mm.
3. VW mode.
Let's start from performance:
PERFECT accuracy up to 140 W, then restrictions start to work.
Voltage shape at 30 W:
What a peak at the beginning? Hmm, let's check other power setting:
Same... Maybe other coil? Let's get the 0.3 ohm braid:
Again: EACH puff starts with ~7 V voltage peak. It is especially severe at lower power - as you can see above power of this peak is 8 TIMES higher than set! So the x217 shoots of the liquid. Deeper investigation of this "phenomenon" is in this film:
X217 has two "pulse" modes:
I don't know FOR WHAT such strange combs?
Fortunately, there is the CURVE mode (actually five of them), which are set in most clear way I've ever seen:
And the result:
Perfectly BUT also with the peak at the beginning.
4. TC mode (SS316).
Dry wick:
Shoot first, than quick voltage drop to 0.3 V. So the wick stays white.
Slightly moist wick (third puff after soaking):
One second and voltage drop to 0.3 V again. Too quick, the wick was still quite wet. The best way for using temperature control is TCR mode.
5. CONCLUSION.
It COULD BE quite good mod, with huge energy capacity and quite solid build. But because of voltage peaks at the beginning it is USELESS to me (especially at lower powers)!
What I LIKE?
* doesn't matter because:
What I DISLIKE?
* voltage peaks at the beginning disqualify it.
