I have owned one of this for about a year now and could not agree more with your assessment and description. One ProVap EZ is about as fast as 3 ProVaps and dare I say 4 in some cases. Yes they are a bit pricey but well worth it if for the sideliner and above beekeeper who is treating colonies by themselves. When it comes to customer service and a great attitude, Larry is not only a breath of fresh air, he is all over it and goes above and beyond to satisfy the customer. :thumbsup:
