Good & Cheap

Rating:****
The capacity is only misrepresented in that it is labelled as 5 oz (weight) when it should be 5 fl oz (volume). It will hold five fluid ounces, but whether it will hold five ounces will depend on the density of what you put in it. It will not hold five ounces of feathers, but it will hold slightly more than five servings of Hammer Gel. One 36 gram serving times five equals 180 grams and I just filled mine with Raspberry gel, using a dieter's scale, to 190 grams (6.4 ounces) with a small amount of room left. The markings on the side are not accurate, but they're close enough for their intended use. "Math Expert" made the same volume/weight error in his review of the 26 serving container of Hammer Gel.

Negative Reviews:

Flask servings misrepresented

Rating:*
This flask was purchased along with the 650 ml bottle of Hammer Gel. The markings (1-5) on the side are supposedly to represent ounces. The website says it holds 5 ounces of product. I poured water into the flask up to the 5 marker and transferred it into a measuring cup and found it's only 4 ounces. Furthermore, the claim that it holds 5-6 servings of Hammer Gel is incorrect. One serving of Hammer Gel equals 1.25 oz. So all you really get in terms of servings from this flask is about 3. Also, be aware that the 650 ml bottle doesn't yield 26 servings at 2 tablespoons/serving. Do the math yourself and you'll find out that 650 ml is about 44 tablespoons or 22 servings.
