LOVE my Citi Mini!
The first time I saw it fold I knew it was the stroller for me.
1. No, I don't actually use the saftey straps (though no doubt you are supposed to). If I'm going to have the stroller open for a long time (like days) without folding it up, I will snap them, but rarely do it.
2. I have to push REALLY REALLY hard to get mine to latch. And the wheels do have to be aligned a certain way. If you have accessoreis I'm wondering if maybe that makes a difference? Again, the only time I've latched it is when I absolutely have to (like checking it on an airplane).
3. I had a parent compartment thing hanging from the back but I found it annoying so I took it off. So I have no accessories. It'd be nice to have a drink holder for me, but I get by.
My son is 2 1/2, 35+ lbs and he climbs in and out by himself these days. And I can still hold him in one arm and fold the stroller in the car with the other hand. It's a great stroller.
