I got lucky on my glass order too.All together i got 40 replacement glass to cover the different tanks me and my son have,and out of those 40,only 1 had a very small chip right at the edge,not even big enough to worry about,i only noticed it because the way the light hit it while i was checking them all.Talk about a boring task,going over 40 pieces of glass tube is extremely boring haha.I had 25 glass replacement tanks arrive today and I think ONE might have a tiny chip out of it. Can't find the chip but there was a tiny shard of glass in the packaging.
Pretty amazing. I have has a bunch of different shipments arrive containing replacement glasses and have only recieved one broken thus far.
Edit: I am averaging 2-3 weeks from order to receipt in Canada provided nothing is backordered. Not too bad.
About a year or so ago,i did get an order with 4 out 5 tanks all having big chips out of them due to very poor packaging at the time,all 5 were stacked end to end on each other and wrapped in paper haha.They were super fast to get replacements to me on those though,and this last order,i see they finally wrap them in bubble wrap,and don't stack end on end anymore,so they are learning haha.
