Plastic viewing window did not fit
We have purchased 5 flow hives and have been happy with them. We purchased a single flow hive super to put on some frames from another company. The clear plastic single viewing window on the side, did not fit the inside space for it. We had to sand and whittle the wood so it would fit properly. There is also a gap between the door that comes off to view the flow supers and the wood piece above it. It's a bigger gap than our other Flow Hives. We just thought we should mention it to you. On a brighter note, the bees have really taken to theses flow frames, after having been on for just a couple of days. I did paint them first with melted beeswax and gave them a jar of sugar water to get them started.
