The slatted rack is very well made. Can't say yet whether it has any impact on swarming or temperature control in the hive, but I have decided to add slatted racks to all my hives.
as described , seems well made.
This piece of equipment has lots of differing opinions. We’ve had success with them, why change something that works.
I ordered slatted racks ,medium sized box and plastic frames. The order arrived quickly and everything was fine. Good quality of wood on the slatted rack and box. Will consider Perfect Bee first on my next purchase.
I was surprised at how quickly these arrived. They are very well made and the price is very fair for the quality. These will go into hives that I will be setting up in Spring 2021. If they work as advertised, I'll be ordering more for my existing hives.
