The lid is nice and high and while you could not marinate a 7-lb chicken, you could marinate the pieces.

Right now, there are over 20 homemade muffins stored happily on the counter in this container.

So many uses!

Having said all that...sometime after buying and using it, happily...I found that marinating meats (this doesnt work as well with chicken on the bone) is much easier and space saving if i put my meat and marinade in a ziploc...get all the air out and seal it. It takes up much less room in the fridge and requires alot less turning because when you remove the air the marinade surrounds the meat (depending on the thickness) more effectively.

I would say this is a good tupperware product if you need something of this size for multiple uses..and can justify using it many times for many things. I wouldnt buy it just for use to marinade or just for storage. I think if i had to buy it again..I would want to be able to say that I could use it several times a week for storing (baked good, maybe deli, snacks) marinading, transporting items...etc. I think that is the only way this would make a *solid* purchase.
