Anybody using inkbird co2 controller?

[Redsusan]

I've always want to gas the girls , but startup costs were a slight deterrent. The inkbird has been in my AMZN cart for awhile, and now 30% off!
Has anyone been using one? Anything worth noting about it? Set up oddities?
Reviews mention .....no light sensor/needs timer...no log data... variations in readings.

Happy New year to everyone!
