Inconsistent Pre-Mixes?

[D4u2s0t]

Has anyone else found any inconsistencies in the pre-mixes?  I have seen a few members post about this, but I don't remember who or where.  Some of my first orders included a few bottles of doppio espresso... the first bottle had an amazing coffee taste, and I loved it... the 2nd one was different, but I had read that tastes change, your taste buds adjust, etc., so I chalked it up to a rookie taste palatte...  no biggie.  discontinued product, not worth calling cs about.

Now, I have 3 different bottles of double apple shisha, and they are all different...  I have a 10ml, a 30ml I got brand new from a trade, and a new 30ml bottle I just got from the yo-yo. and they are all 100% different...  The first bottle tastes like it should be called "shisha" and they forgot the apple...  the first 30ml bottle was awesome, had a very strong apple taste, and it has been the only flavor I can vape all day so far.  Actually, I haven't put it down since I got it about a week and a half ago, love it.  The new ones are different, it's a blend of the apple and shisha, which  Iwould assume it should have been all along... 

So, down to the question.  Do other members find this inconsistency? I ordered 5 bottles of this in the last yo-yo, based off of the other bottle I had, and I'm hoping they're all the same, otherwise I just spent alot of money on a flavor I can't stand...The last one had a more reddish color, and the current one has a more yellow color...  Can there be that much variation in the pre-mix?  I'm just hoping I didn't order 150ml of a liquid based on a bottle that was not correct...
