I've recently discovered SLIMFAST and have tried these flavors: Cappuccino Delight, Caramel Latte, Bananas & Cream, Creamy (Milk) Chocolate, Strawberries & Cream, and French Vanilla. Caramel Latte is my favorite flavor.
While CARAMEL LATTE is my FAVORITE FLAVOR of those I've tried, it's my LEAST FAVORITE when it comes to OPENING THE BOTTLE! All other flavors open with similar reasonable effort, but CARAMEL LATTE requires me to use a wrench in order to remove the top! I'm no 90 lb weakling, but without the help of my favorite WRENCH, I'd never be able to open my Caramel Latte bottles! Is this a result of the bottling machines being set incorrectly? Are all SLIMFAST ADVANCED ENERGY flavors too hard to open by hand? I don't know, as the Caramel Latte is the only ADVANCED ENERGY (with caffeine) flavor I've tried.
Using only my wrench to open these bottles is an improvement over my first attempts, where I had to carefully secure each bottle in a VICE before I could successfully open it with a wrench.
When taken from the refrigerator, each bottle is coated with condensation. If not blotted off, the condensation makes it impossible for me to get a good enough grip on the bottle in order to twist the cap off. While my vice has removable rubber pads on the jaws, it took much concentration for me to avoid splitting the bottle by over-tightened the vice. Once sufficiently tightened, I had to support the mounted bottle with my other hand to keep it straight so it didn't rotate when I applied counter-clockwise pressure from the wrench to open it.
This VICE-WRENCH procedure became too much of a project for me, so I wiped off every bit of condensation and gripped each Caramel Latte bottle with my knees, added support with one hand, and twisted the wrench to open it. I learned that twisting the wrench quickly is more likely to break the cap-to-bottle seal than if I use the wrench in a normal manner and apply increasing counter-clockwise pressure until the seal is broken.
I've been through 3 cartons of 15 bottles of the Caramel Latte and each of these 45 bottles has required a wrench to open. NONE of the other flavors is difficult to open. These 3 cartons of Caramel Latte were purchased at the same time, so I don't know if SLIMFAST has changed the setting on its bottling machines. I hope they have, but I'll still keep my wrench handy, just in case.

PS: RE: CARAMEL LATTE: This flavor reminds me of the Coffee Ice cream sodas I used to enjoy as a child. I'm not using SLIMFAST as a diet aid, but when I drink a bottle between meals, it's much easier for me to wait until mealtime to eat instead of snacking continually to keep the hunger pangs away. Whenever I drink a bottle of Caramel Latte, I think of the weight problems I'm avoiding if I had a coffee ice cream soda instead of this SLIMFAST substitute. I give SLIMFAST a 5- STAR RATING because it does what it says it does. SLIMFAST makes NO CLAIMS as to the ease or difficulty of opening its bottles.
I gave SLIMFAST CARAMEL LATTE 5-stars for each of the three listed features (Flavor, Value for money, and Easy to hold). I would rate a fourth feature, "Ease of opening" 1-star if that feature was added to the list.

Very good

I appreciate you keeping the price reasonable. It seems most sellers, have been jacking the price up. I assume that is because they are in high demand, and harder to get. I assure that I always pick the seller with the cheaper price. So, thank you!!

The product box was tore so items fell out

The caramel latte flavor is my favorite. I put it in the freezer for about 45 minutes to an hour, shake well and its like a shake, so good. I drink one in the evening an it helps with my night time cravings.
