Query: Not good for moderately heavy purchases

I bought this - more expensive - cart after my $20 cheap one fell apart on my way home last week. The cart was reasonably easy to put together, and when empty, it works well.But, when you put things in it - even moderately heavy loads - the front wheels lock up, and because of the propensity of the wheels to roll under the cart, the cart becomes unbalanced from the front, and wants to fall over towards the front all the time.I got this cart because I carry water and soda about half a mile home after supermarketing. These are very typical loads.Don't believe it when it says it can carry 200lb - rolling on a smooth surface maybe - at a push.However, if you want to use this cart to carry loads home - on pavement and walking across roads - this cart fails miserably.The last time I used it, I literally had to drag it behind me because of its propensity to topple over at the front.My advice - DON'T BUY THIS CART.
