If you really want a Flow type Hive, you can buy one called an automatic hive from Ali Express for 368.00 USD delivered by DHL.
I bought one and giving it a try, I will transfer my NUC to it in a week or so.
I was not aware it was a knock off to Flow until after I bought it, but there were no issues except.......I had to do a little hand work to each dovetail joint and a few screws were missing.
Then I watched a video on Youtube of a guy assembling a genuine Flow Hive, he had the same issues plus a few others.
Flow will tell you the plastic in the one from Ali Express is not Food Grade plastic........that is not true, I have copies of the lab report certifying it is in fact Food Grade and will share that if anyone wants to see it.
