I had a TBH and, I'll have to disagree with Robo on this one, it was my gentlest hive. I captures a swarm (yes, in africanized territory) and hived it in the KTBH. IT was by far, easier to work than all the other langstroth hives. Despite being in full sun for half the day, I never had a single comb collapse. My problem later became the screened bottom as, being a weakpoint, some predator/s managed to rip through it and tear apart the colony on December 23rd. One notable feature is that, it takes me about three to four times longer to fully work and inspect a top bar hive. I'm in the process of repairing/rebuilding it now and, hope to have it back up by this summer.
