I have a ZZ2 for my syrian and I do love it.
The lid on mine is meshed and I'd also advise having a few washers, screws and bolts handy because one of my old syrians did decide the cage was for eating. She made some little holes in the corners but I just put washers over and it's unchewable now
I put in a washer and screw to cover the water bottle hole too. Mine's the old white cage, I assume the newer ones still have chewable bits but someone might tell me I'm wrong
