I am an original eRoll user for 3+ years. Tried the eRoll C and hated the metallic tips that left a metallic taste in my mouth. Other than that, I saw no benefit to the C version.
I purchased the Ovale eMini Duo despite not being able to find any user reviews of the product.
I actually left a glowing review of Ovale eMini Duo during the first week of its use which was brilliant, when it worked. As soon as it was time to replace the atomiser, things went downhill. That was 3 or 4 months ago.
I can now confirm it's overpriced rubbish.
1) Its expensive! (See point 6 also)
2) No matter how many times I change the atomiser and the cartridge, it bubbles and leaks liquid into my mouth within the first 30 minutes of use.
There are connectivity issues, if things are too tight, you get no burn at all, so you are constantly screwing and unscrewing the many elements and many of those components have rubber washes (Unlike the eRoll)
3) It leaks liquid into the battery and the metal ring that connects the battery to the cartridge.
4) Its not automatic, and I dont like having to hold a button down on the draw, I like the natural feeling of an auto mini cig as its more realistic to the real thing.
5) The company are expensive and rude. I fail to see why they need to charge so much for their products compared to a company like Joyetech
6) On that note, I purchased the eMini Duo based on the photos and name (Duo) and assumed like its predecessor that the kit would come with 2 devices and parts to match. It came with one e cig and no spare parts. The PCC is designed to charge 2 devices at the same time so why only send it out with one? Plus as I say the marketing images lead you to believe you would be getting two e cigs. It certainly costs enough to expect that.
Bottom line is I wasted £180 on the device and spare parts and it has been thrown in a drawer and I have gone back to my eRoll buying up spare parts where I can find them or buying Ovales version of the eRoll which is called "eMini"
Further more, in my quest to find cheaper atomisers for the eMini Duo, I discovered Eleaf iKiss pen as it uses the exact same atomisers. It looks exactly the same too only much cheaper and so I ordered one and I can confirm these e cigs are identical in design, atomiser types and they're both as bad as each other in terms of leaking and bubbling.
But at least the iKiss is cheaper so you don't feel as if you have been totally ripped off.

Save your money and buy something thats been around for a year or two and that has plenty of independent reviews
