I'm a past one year vaper, and i use to vape using Ego batteries (mainly with Ego-C, Ego-W, 510LR atoms dripping and Boge 2.0 cartoms)..
But i own an original Ovale Elipse since one month and a half: i think it's a great vaping: flavour (very pronounced), hit and big vapor... yes, the battery is only a 350mah, but you have two of thems in the kit; also i bought some low price clones: the Elips ELF which has identical structure (i mean, the batteries and the atoms and all the rest are interchangeable with the Ovale). This clone performs more poorly compared to the Ovale, but the batteries (other two of them) are identical !
I also bought another clone (the Elipse F6 LSK) that should arrive tomorrow; but i already know that this clone is not fully compatible with the Ovale..
Sure, the Ovale atomizers are highly priced (in Italy, abroad i've seen they cost less); but i can assure that they last (i'm still using the first two ones); also, they are easily cleanable, there are some videos on Youtube on how to do that.
In the end, i mainly bring Ovale with me when i'm out (and maybe an Ego-C, just in case...)... the form factor, the flavour and the TH does not let me desire other when i'm out... at home, different story, i mainly use all the hardware i bought in this year of vaping (i paid and i should use them, right ?); i recently got an Ego-C Twist VV battery also.
Right now that i'm writing i'm happily vaping the Ovale Elipse....
I use Ovale and FlavourArt juices (i'm from Italy).
I highly recommed the Elipse for outside use, that's my opinion though
p.s.: 650mah batteries for the ELF Elipse clone exists, and, as i said, are fully compatible with the Ovale ones.
