I built the Simple EX last night, juiced it up this morning. Liking it so far.
Built the RDA with a 30g, 6 wrap, 2.5mm kanthal coil. Came out to 1.53 ohm. If you roll your own coils, roll them COUNTER-CLOCKWISE. I usually go clockwise, and with small wires, it's hard to clamp them down when you have to flip the coil. Also, with small wire, screwing down the leads can be difficult, the screws like to kick out the wires as you tighten them. Haven't tried the included coils yet, but they do look nice.
So far, I'm running the RDA on the third largest hole, only run it at 3.3V, and using 24mg freebase juice. Been vaping it all day instead of my full size setup and it's really nice.
Main complain is the squonk tubing is carelessly cut, just like my Pulse was. Cut very rough and at a high angle, so you can't easily squonk the bottle empty. This is more important than on the Pulse since it's a smaller bottle. Mine was a little long too, so I just snipped some off the tip where they cut it for now. I have some spare tubing, I will probably cut a better piece in a few days if I continue to like it.
I really am surprised how small this thing is. At the same time, the Pico Squeeze with an Ammit RDA on it is already pretty small. I'll try to post a picture for comparison later. Very light though and easy to forget you even have it in your pocket. I'll weight them both later too if the batteries in my scale still work.
With the Squeeze, I rest three fingers on it, with the Simple EX, I have to hold it in the upper part of my hand to fire it easily. In a way, the Squeeze falls into place easier in my hand. With the Simple EX, I have to shift it up to hold/fire it because it's a good deal smaller. Very comfortable though, and the fire button is nice.
As was mentioned in DJLSB's review, they released it with a stiffer bottle. Still appears to be silicone, but it's not too soft where it's too easy to squonk small amounts. Bottle seems to be good for the application.
Battery life is good so far, interested to see if it will get me though the whole day. Started off freshly charged this am, and still have three bars (out of five) left at 3pm.
No leaks at all, even in the 510. Mine seems like all of the juice goes right into the RDA. No issues with oversquonking/leaking. Been pocketing it all day and no problems.
I do like it, no regrets yet but only been using it since this morning. I'm not sure one of these would buy you much if you are running a Squeeze/small RDA for the same purpose. If you are looking for something smaller, then by all means, it is. LOL. I do like I can run a higher cpacity battery in the Squeeze, and that the battery is replaceable. If you didn't have a Squeeze, or was just starting out with MTL squonking, I don't think you can go wrong.
Pretty cool little device. Folks moving from a pod system to this as their first rebuildable/squonker should be very pleased. Even on 3.3V, and 3rd hole from the smallest, this thing vapes better than my Minifit using a 1.5 ohm Kanthal coil. Good vapor production.
