The size and form factor are very good. It's a solid, hefty feeling piece of kit that feels good in the hand. It feels just about perfectly balanced with a Hcigar Keyfun 3.1 clone on top. Not too top heavy as I feared it might be. The matte finish is almost soft to the touch. It's very nice. The polished trim on the MOD and screen border nicely. It is done sparingly, and complements the button. It's just enough flash without going anywhere past minimal. The threading is very good, but not in the same class as some other MODs (The Roller, for instance, where the threads are butter).
The controls are easy. Do not let the tilt function sway you from this purchase. It's not terribly finicky and the controls are intuitive. It took me about 1 minute to master changing wattages to where I'm exactly on where I want to be most of the time. When I'm not exactly on, I haven't been more than .2w away, and that was only once. I wish there a few more options in the settings (pre-set wattages for different attys or eLiquids, the ability to set backlight time). The screen is easily readable in "dim" mode even in a very brightly lit room. Being in the sun may, however, prove seeing the "dim" screen difficult. I DO NOT like that you have to push the fire button to see the fully lit screen, and to make it worse, it dims IMMEDIATELY after releasing the fire button. I'd REALLY like the ability to set that myself. 5-20 seconds seems like it would be a good range for me. Unfortunately, it's instantly. All of the information on the screen is easily readable and it's layout is nice. It gives all of the information you want, and presents it logically. It seems a better presentation than the DNA systems (from the pictures I have seen as I don't own a DNA chipped MOD). I cannot read the screen when vaping with a Kayfun. I'm with Busardo: I hate the flash screen when you power the unit up. I know what brand MOD I bought, and I don't need to see which chip controls the MOD every time I turn the thing on. I also hate the SIGELEI logo directly underneath the fire button. If you're going to do it, do it right. The very generic SIGELEI logo cheapens the MOD on the otherwise sleek look of the MOD. If they had an interesting logo that would add character to the MOD (like many independent MOD makers have) it would be fine, but their logo is that of a technology company with a bland presentation.
The fire button itself is good. Not Great, but good (The Roller has set the bar for what I consider a great button). It has a firm tactile push, and it isn't very picky: even pushing the button on the edge fires the button (that could be good or bad - I see it as a good thing as this is a "basement" vape, and having to press the exact center of a button is annoying in the dark). It has a bit of wiggle, but not enough to be overtly bothersome. It also rattles very slightly. I'm currently watching TV at a reasonable volume and I can hear rattle, but only when I put it up to my ear. When I hold it at keyboard distance from me, I cannot hear it.
Currently I'm vaping Rocket Pop by Rocket Fuel Vapes in an Hcigar Kayfun 3.1 clone with a 3/32" micro coil using 28g kanthal (9 wraps) at 1.7Ω (1.69Ω on the Ω meter) with my wattage set at 10w. I'm using the big 30A, 2600mah, 18650 Sony. It's vaping smoothly, and simultaneously like a beast. It easily the best vape I've had yet (disclaimer: I haven't been vaping with MODs and RBA/RDAs for very long so my sample size is small).
This Sigelei seems like it's going to prove to be a very nice MOD at a very good price. I ordered from Fast Tech. It took 1 day for them to ship, then another 8 for it to get here. 9 days from China ain't too bad.
