yes, I’ve been using it for years. But only for racing and longer outdoor training sessions. Mainly because you need less water/g carb. This is an advantage for longer races.
Solubility can be a pain.
Given the higher cost I don’t see any other advanage to a regular maltodextrin mix. I buy bulk maltodextrin. Mixing ratio is 2:0.6:0.4 maltodextrin:fructose:“some sports drink (basically for flavour)”. This is what I use for my indoor rides (where fuelling is actually needed)
