"I've ordered the 1250ml and the 4000ml tub. The 1250ml was able to fill to the brim the Creapump (750g), but the 4000ml wasn't able to completely fill the Impact blend (2.25kg), it probably would with the 6000ml if I had enough money for it. But yeah, it's a great product, very beneficial and I look forward to purchasing the Item again if need be. A+"

"AMAZING PRODUCT, complete time/ life saver. I ordered the small tubs ( 1250 ) medium ( 4000 ) . secure tubs and good lids. small tub held creatine monohydrate 500g, took up most the tub. essential amino acid 500g went to about 3/4 maybe slightly more. branch chain amino acids (BCAA) 250g, took small tub to around 1/2 to 2/3 full. maybe slightly less. but don't think 500g would fit. medium tub filled 4/5 or above with 1 kg melon whey isolate. hope this helps some of u guys get a rough idea of contents that can fit in each. the medium (4000) tub don't quite fit in most shelf in kitchen cupboards, so the larger size (6000) will defo cause storage issues. fantastic product 6* even."

"Absolutely got to agree with Louis Wiltshire -- these are much better than the ""clip-top"" tubs MyProtein USED TO sell. There are the same brand of tubs you get when you order protein in a tub from the MPMAX range -- which are really durable, and the screw-top lid is fantastic. Here's some information about powder sizes for people considering buying (and please, any future reviews, tell people what size you got, for what product, and how much of the product!): - 4000ml is great for 1kg of Creatine (the actual volume of the powder is closer to 2500ml) - 1250ml is MORE THAN enough for 100g Multi Vitamin Powder, in fact, 500ml would be sufficient!"

"Recieved three of the 4000ml tubs and must say I am very pleased. The tubs I recieved were opaque (not a problem) and the screw on top is second to none. MUCH better than the older tubs provided by myprotein. A must buy if fed up of carrying protein bags around and would prefer them in solid, secure tubs."
