Hand truck. What do you have and do you like it?

I have one I got from costco. Like previous post it can lay flat and roll with four wheels if necessary. Made from mostly aluminum so it's relatively light, and won't rust. It has big tires, rolls well, but I don't know if they are flat free. It's a little bulkier than some, but seems pretty well-made. I think it was like $80, a little spendy but after using it a few times, I don't mind.
as a follow up on mine, it is a COSCO brand, which I bought at costco. Model 12-326 ASB, "3-in-one", if you want to look it up online.

PS. mine is just a little different than the one in the link. It doesn't have the individual handles like the one in the pic. Mine has the so-called "D-style" handle, which I prefer.
PPS: I think it does have never flat tires.
