A great rum for mixing. I found it ok by itself, but not as good as other MG rums, most of which seem smoother. Possibly the best mixing rum I've come across, Eclipse does what it says to other similar priced rums.
My one regret was not keeping the bottle.
(Same rum so same review)
My go to mixer. Great with coca cola, ginger ale sprite and the like. Mixes well with practically anything. I've tried many rums over the years, but Mount Gay Eclipse is always what I return to for a great mixer.
