You know, it's just laziness on my part but I can't be bothered putting in a support ticket. The shipment before this one had a couple of replacement glass
tanks in it and both were the wrong size. Customer support argued with me that they were the right size - went back and forth several times until they realized they'd sent me the wrong ones.
I don't know if it was a language barrier thing or what but I don't have the energy for that again. This
rta comes with a spare glass and I happened to have ordered an extra one as well.
