I am in the market for a small APV and have been reading up on these 3 models as they seem to be the smallest models with replaceable batteries that are out there.
I was wondering if anyone can give any current info on some or all of these?
I have 3 iSticks so please don't tell me to get one of them but I do have a bunch of 18650s so I would like to get a mod that I can use them in
and I have more attys than mods at the moment 
I don't need more than 30w as I have mechs if i want to go that route.
I am looking for a Spring loaded 510 pin, Easy battery changing, Reliability, Cost under $100 and Accurate chipset.
So after looking at all of these none of them are "all I ever wanted" they all seem to fall short on one of these points
Cloupor Mini
510 screw (not left handed) -
Smallest in size of three -
Battery cover is report to be "clicky" meaning when you pick it up or push on the cover or shake it a little there is a clicking sound
Magnetic battery cover -
Bad reputation - seen mentioned many times as "crapor" -
smok XPro M50
Spring load 510 -
2nd smallest in size -
4 screws to change battery - 4!? PITA!
Rep is rather neutral -
sigelei 30x mini
Spring loaded 510 -
Largest in size - It looks huge next to the Cloupor
Magnetic battery cover (and a rubber jacket for it) -
Rep is very good -
I really like the size of the Cloupor but after all the reading of people blasting them I am not sure I want to spend my money there. Have they fixed the issues with the chip yet??
The XPro M50 look good as well but OMG 4 screws to change the battery!? I am WAY too lazy to be bothered with that! And someone mentioned, it "felt" cheap. Is this true to anyone who owns one?
The Sigelei looks good but I really wouldn't call this a "mini". I mean maybe comparatively speaking with their other models but not when compared to the iStick or the Cloupor. it is way bigger.
So is there any feedback anyone can give me on any of these? Likes / Dislikes, general thoughts and ponderations?
