"I purchased the 4000ml tub for my 1kg of impact whey. First of all, the tub (4000ml) is well made and a good size to fit on any shelf or in any cupboard. The 1kg of impact whey filled the tub approximatley 90%, so for anyone wondering how many kg's of protein the tubs can hold, I strongly reccomend 4000ml per kg as a benchmark. Very happy with this product and I'd recommend it to anyone :)"

I bought the 10000ml tub and it's well made. For anyone unsure of sizes I posted a review for this tub which include pictures here: http://community.myprotein.com/supplements-formulas/39699-review-10000ml-tub.html#post555258 If I needed more I wouldn't hesitate to buy these again.

"i ordered the 6litre tub because my bags seal ripped, i put the rest of my hurricane xs in the tub and it really helps to keep it fresh, not too big to fit in a cupboard also very cheap for the quality "

"Ordered two 6-litre tubs, 1 kg Impact Whey Protein, and 2.5 kg Instant Oats. The 1 kg of whey protein fills about a third of its tub and the 2.5 kg of oats fill about two thirds, each perfect for when you need to resupply but have some left at the bottom. Very good tubs, well-made, screw lid is easy to tighten and undo and never comes loose. I suggest getting the 6-litre over the 4-litre because the extra literage is well worth the added 50p in price, unless you like to shake it up at the gym - they're fairly big tubs."

"i got 2 6000ml tubs and they fit 2.5kg of whey perfect and even 5kg of instant oats but the oats you need to push down and flatten out to fit 5kg into a 6000ml tub, work really well there plain white nothing else to say really beats keeping oats n whey in a bag incase bag bursts or rips"

"This was my first purchase with MP and I am very impressed. Delivery was super fast (ordered on Bank Holiday Sunday and delivered on the following Tuesday). I ordered 1 x 6000ml and 1 x 1250ml tub, along with 2.5KG Whey Protein Isolate (Choc Smooth) and 750g Creapump. The 2.5KG Whey fits perfectly into the 6000ml and the Creapump fits nicely in the 1250ml, with room enough for a large scoop, bonus. Tubs are nice a sturdy and the screw top lid fits nice and tight. Well worth the money."

"Excellent product, bought it on the ground that people had reviewed that their pouches had ripped. 5kg of Impact Whey Protein fits nicely into 2 6000s and a 4000 with a little space left over."

"5k oats didn't fit at first in 6L tub but if you leave it for like 1-2mins, it settles down and you can add the rest in =)"

"GREAT product for keeping your powders secure and fresh, HOWEVER i ordered the 1.25 litre tub and 1KG of powder DOES NOT FIT INTO THIS Otherwise great product!"
