I've been using glass with success for almost 20 years. It's not hard. It just takes a little tweaking to set up, but there are plenty of tricks. Once set up and dialed in its easy, honestly.
That being said, I'm slowly upgrading to PVC caging and Radiant Heat Panels. Why? They're even easier. No lamps. I can stack them and consolidate them. More snakes in less room. No more glass enclosures all over the place.
But....until you get more snakes that won't be an issue...
There is ABSOLUTELY nothing wrong with glass. Millions of people are using it with success. Some folks will say glass stinks, but honestly, it's really easy after a few simple tweaks.
I'd be happy to share any info you'd like if you decide to go glass...
