Each strip only contains 50mg caffeine (half of an espresso) so the effect is probably mild even if it's released all at once, let alone slowly. The strips are rectangular and the corners briefly poked me in the mouth, but it dissolved and softened immediately. The flavor is minty artificial mango. Not amazing but not bad either. It leaves a gel-like coating on my inner cheek while it did its thing, but otherwise stayed out of the way. Whole thing probably lasted 30 minutes. I do feel awake and alert writing this, some time after it dissolved completely, and I don't feel any jitters or other bad side effect of caffeine. So it seems to do what it advertised to do. It's also very very light and compact, so perfect for stashing in the purse for quick pick-me-ups. I love having a dry source of caffeine in my purse (also because with liquid coffee, I'd then worry about having access to a restroom, but not dry caffeine).

All in all, it seems effective and very useful, and I have no complaints, so 5/5.

These Mango Tango Energy Strips are quite an interesting little way to get a caffeine boost. Each strip provides 50mg of caffeine, which is a bit less than a regular black coffee, but the unique strip format makes it incredibly convenient.

I typically use one in the afternoon when I need a pick-me-up and don't want to drink a whole cup of coffee. They're a great alternative for a smoother, sustained boost, and I appreciate that they're made in the USA, with no added sugar, and are vegan and gluten-free. It's a really unique and effective way to get that bit of extra energy when you need it!

I really like these strips on how they're packed individually so you can take them on the go. I quit coffee for my stomach issues and also just to not have to deal with k-cups and creamer and all that. But I still like to take some caffeine these strips are great they taste good easy to use very convenient to travel with and to keep on the go for when needed and I think the amount of caffeine is perfect like a cup of tea.

The small package is very easy to carry. I can take it along with me without taking up much room at all. The strips taste ok. I think I would get a mint flavor next time the mango is acceptable. The strips are pretty strong. Don't take too many because they will sneak up on you. I like these. I will keep using.

I am enjoying these STIM Frost Mint Energy strips. The Spearmint flavor is minty and fresh like a breath strip. Each individual strip has 50mg of Caffeine and is easy to take. The instructions recommend placing on the inner cheek and allowing them to slowly dissolve. I quickly feel the energy boost that these give.

Each strip comes individually packaged, making them easy to toss in a purse or pocket and keeping them fresh. Once the package is pulled apart, peel the strip off the packaging with dry hands, balance it on a finger and place it into the mouth aiming for the cheek.

I'm really digging these mango caffeine energy strips. They are very handy to have on hand when conventional methods of ingesting caffeine aren't possible. Don't let the pictures fool you. This pack of strips is teeny tiny. That's not a bad thing because the fit in a pocket or purse with ease. The flavor is pretty darn good compared to others I have tried so I'm really happy with these. Great product!

As someone who drinks a ton of coffee and energy drinks, these are great. I don't get a super rush from them, but I also don't feel the need to constantly look for my drink. The fresh mint is very nice, and they remind me of some mint breath strips that I've had in the past. They came with each strip individually sealed and the packages peel open from the top corners exposing the strip. The strip slowly dissolves in your mouth and leaves a fresh minty aftertaste. I've already thrown a couple in my car and a couple in my travel bag for those quick fixes I get when I'm out. Each strip says it contains 50mg of caffeine, and you're not supposed to consume more than 5/day. For reference, the full size M energy drinks I usually drink have 160mg of caffeine in them. I have not felt jittery at all since I've started using them, and today as an example, I'm 4 in for the day so far.

I had the chance to try this for over two months now and it's now part of my routine. I need to drive 12 to 18 hours straight for my job and I used to survive on energy drinks to keep going. Hated the bloated feeling from drinking so much. With STIM, it's much more convenient and I can carry it around in my jacket. I use two strips at a time but I guess its up to you. Definitely recommended to all my fellow drivers and truckers.

I keep this close by whenever I need a quick energy fix. I don't really like coffee and other energy supplements don't work for me. Will get more.

It's something different for sure. The strip dissolves pretty quick on my cheek but it leaves a slight residue which I just swallow after around 10 minutes. No big deal but it doesn't dissolve completely. Energy increase was ok, I use 2 strips at once sometimes but that's me.

Tried all three and Mango was the best. The flavor was not too much and felt a bit like mango and pineapple?? The other two were pretty good too although Mint was a bit sweet like spearmint.

Tried it and I do get a lift, not sure if I'm imagining it. Will continue to use it so far it's all good.

It comes in more flavors than the others and definitely tastes better for sure. Berry Zest was the best. I do feel more alert but mostly it's the convenience to use it anywhere I need.

The box is smaller than I thought from the pictures online. It fits in the paml of my hand and I don't have big hands I think. One box is 20 strips which is perfect and easy to carry around in my bag... I appreciate that each strip is individually wrapped too unlike some of the others. I think it keeps the taste and freshness better? Idk but it works.

Tried this for a few days and it does work pretty fast. I use one strip before I leave the house and maybe 2 or 3 in the day. It doesn't replace coffee or drinks but it's a good to have within reach when I need to lift myself!
