Works like it should. I bought unsweetened and definitely do not recommend putting it in something sweet as it will change the flavor. There is an option for a sweetened version.

Good except for it’s bitter

I love coffee, but at midlife, my teeth love to pick up stains, and it is hard to brush enough to keep my teeth from being yellow from coffee. I tried the powdered 200mg capsules(used half a capsule for each large cup of water flavor) and it's ok, but leaves a powder residual and has just the slightest(almost old oily) taste. I started using this, the liquid 83mg per 5ml) and it is absolutely flavor free. You can't even taste it by just tasting the liquid. I also found the clear water flavor(the coconut lime generic is amazing) and I can still have the caffeine and I am not having to try so hard to keep from looking like I have bad teeth(I have great teeth, but anytime they are all stained up, it's hard to see it.) I am on bottle #2 and my opinion is not changed. I am looking for a more concentrated liquid to carry in my car for water when eating out, but for the money, this is the bomb.

Once you get past the taste, it does the job.

I have only used 1 pump (pump comes with it) per drink and it works great. I cannot sense any flavor to it at all. It's pretty amazing because you can put a bit of caffeine in virtually any drink and give it a boost but with no after taste.

This product is super easy to use! The pump doesn't fit with all the liquid in the bottle so it's easier to remove some liquid before adding it. It works well and I love that you can customize the amount of caffeine. It definitely tastes bad on its own but you can't even tell it's there in a flavored drink. There is some white coating on the end of the pump after a while as the information packet warns but it's easy to clean off. The design of the bottle looks great too!

Arrived as advertised. Fresh product. Easy to dispense.

Exactly as advertised. Included the pump although it overflowed a little when inserting the pump. They need to leave a little more head room in the bottle. Be careful if you get a lot of it on your skin, caffeine can be absorbed that way fairly quickly.It's completely odorless, colorless and tasteless except for a very slight bitterness. You won't notice unless you're drinking it straight, which you can certainly do if you just need a kick and are otherwise hydrated already. I've mixed it in with seltzer, juice and my morning green smoothie and it works in all three.Bought this because my wife is breastfeeding and can't drink our usual energy drinks because of all the non-caffeine ingredients in them. Now she can have a beverage with JUST caffeine as well as control the amount she's consuming to avoid passing any along to the baby.
