5 Star Taste in a newly competitive market
The world of protein bars is getting more and more competitive, meaning more and more options for us consumers.I'm sure everyone was as excited as I was when Mars announced they would make both Mars and Snickers 'protein bars'Having had 2 boxes of 18 over the past few months, I have come to the conclusion that I both love and hate these bars.Good points:1. The Taste. It's so very similar to a normal Mars bar, it's just slightly more chewy, which is to be expected.2. The Price. Both times I purchased these Amazon had a discount on, so I purchased 18 bars for the same price as most companies sell 12 bars.3. Protein. We all want to hit our macros. 19g of protein is going to help us.Bad points.1. The macros. Let's be honest, they are not amazing. 23g of sugar is not great.2. The alternatives. Quest bars and Grenade bars are both cheaper on amazon and both has better macros (Only slightly).I still would recommend these as a great treat on your diet and still give them 5 stars as the taste/price/macros are all worth it. Just a few years ago the options for protein bars were terrible, we need to encourage companies like Mars to stay in the game.

A bit too good
Not the healthiest protein bar you can buy, but definitely the best one i've ever tasted, and i have tried quite a few. Tastes a lot like a regular mars bar, but with a bit of a firmer texture, which i actually prefer. With 23g of sugars, it's not exactly healthy, but should still be preferable to candy, as the protein helps with your overall macros and might keep you from being hungry for an hour or two between meals. I probably won't be buying them at their current price though (27.5£), whereas the price i bought them as a black friday deal (15.99£) was more than reasonable.

My son goes to the gym daily and he likes these as they give him a protein boost. I did try a bite and it tastes okay, not quite a 'Mars Bar' but not far off.

You can't find a better price on the internet
I have these on subscribe and save via Amazon. You can't find a better price on the internet, let alone in the shops.The macros in these bars are superior to most other protein bars. They don't taste as good as an original Mars bar because they're not loaded with sugar and do have a slight gritty taste. BUT, they are in my humble opinion pretty amazing. My other favourite protein bars are Grenade, Oh Yeah and the Quest strawberry and white chocolate. But this is my bar of choice. I've tried a lot of protein bars so I speak from experience...

Great Bar. Can be pricey. High sugar.
Taste almost just like the original with added protein hit. Can be pricey but great if you want protein and a more substantial snack. High sugar though, so watch this if you need to reduce sugar.

Believe the hype.
Only 200kcal for 19g of protein and it does taste quite like a Mars bar. You can tell there is whey in there, obviously but they've managed to make a great tasting bar that you could give to your non-lifting friends without having to apologise.No increased bathroom visits either which is always a must for me...I didn't buy these super early, when everyone was going nuts over them. I only paid around £15 for the box, which is a good price for any protein bar.

Decent way of getting protein but not, sadly, the Mars Bar I'd prefer. Such is life!
Giving this three stars because of the strange white bloom on the chocolate which is harmless but off putting: they need better storage before sale. Otherwise would have four stars because I need to gain weight, but can only eat small amounts. This is a much more palatable way of getting a good amount of protein than anything else I've tried ( the milk shake sorts are too filling and some taste unpleasant).When I say palatable, I'd rather have the real thing. This is more like thick firm fudge with very little toffee topping and is chewier.
