"Best of the bunch"
Hands down the best of the liquid sucralose products I've tried (which is at least 7 different brands over the years - probably more). The dropper bottle is actually the best dispenser I've tried yet as well -- you don't get the dried up crusty stuff that the others end up with after a while, and the amount that comes out is always exactly the same (assuming you know how to handle a dropper).
The sweetness is a little more than others I think -- one drop does the job of two of most of the others. Perfect sweetener if sucralose is your thing.
Also great customer service from the seller - I'd probably still buy this one over the others after trying it - but it makes it even better that they're awesome folks too.
