Received my ProVAp 110 yesterday (2/21/18) and treated hives this morning. Quick, easy to use, and no problems at all. Elected to drill ¼” hole in back of the bottom hive body, treated each hive in less than a minute before moving to the next hive. Fact is it works almost to fast by the time I load another cup and place on the next hive I do not have time to get back to the one I just finished to put golf tee in the hole. Was easier to just complete all my hives and then go back and plug the drilled holes.
Longest time was waiting the 10 minutes before opening the hives that had been treated. Very pleased with the operation of the ProVap and almost look forward to treating rather than dreading the long, hot, rather slow process of using my wands. Only other drawback is will I be able to sell my wands.
