I thought I would chime in with my OilVaporizer and W9Tech buying and use experience.
I purchased an Alpha Globe and a 5 pack of dual TiGr2 coils after much research and deliberation based mainly on info coming through these forums.
The good news is the coils work great! I run them at 6.5 volts on my iStick 50 (which has power to spare and absolutely great battery life---4400mah) and they melt anything and everything I can fit in there. Wax, crumble, shatter---poof! I have not yet tried the single coil that comes with the globe by default.
The bad news....the globe glass is very thin...too thin for my liking. I broke the first one within 5 minutes and had to order another. I went ahead and ordered two @4.99 each plus shipping==$19 sumthin... That is too expensive for this glass. If anyone at OilVaporizer is paying attention, I have noticed that W9Tech has a borosilicate globe for the smaller Kiss Globe @ $19.99. I would pay a similar price for a thick borosilicate piece for the Alpha Globe. Make it happen! A metal sleeve would be nice, even a simple straight tube with a swaged mouth piece or a separate drip tip. It doesn't have to be fancy like the Alpha Centauri kit.... Just make something better than the standard glass and give a reasonable price and I'll buy it. I think others would too. As it is, I'm considering having a custom piece made here in Oregon...(big glassblowing community).
I ordered the 1701 (rebuildable) from W9tech and noticed at the time that they were running a promotion wherein if you spent $10 with them, they would send you a free Omicron V2.5 vaporizer. That sounded interesting, so I went ahead and ordered the coil and asked for a blue vaporizer if they had one. They were very clear that the vaporizer they were sending was just a body...no battery, no charger, no atomizer, no box, etc.....
So, the box shows up and it's bigger than expected, kinda heavy too...at least for the one coil it's supposed to have in it along with an empty vape tube. Well, under the packing peanuts and the lone coil was a white box and imagine my surprise upon opening it and the first thing to fall out is a battery charger...next is a hinged, padded box containing one battery, one blue vaporizer, one funnel, one mouthpiece and one atomizer....A full complete kit! And it qualifies for the v4 upgrade available at the end of March!
The 1701 works great, I run it at 10 watts (Thats what DT insists is appropriate) and it just sizzles everything into smoke! It is a little harder to load because of the hole in the middle of the donut...you have to be a little careful in order to keep stuff from melting in to it but I have no complaints. When I participate in the v4 upgrade, I'll buy another 1701 and a pack of the donuts to rebuild them with.
Well, that's it for now, If anyone reading this has had doubts about doing business with either company, put them aside and get in the game.
