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:The provap EZ has got to be the best all around Vaping device available in it's price range. I've used the larger more commercial versions, and the smaller hand held devices. The EZ is the best for not bending over, while still being light enough to handle all day, all while still keeping the ability to vape off the dose in seconds. I'd call it semi commercial becuase i believe the build quality could use some beefing up, mainly for anyone wanting to use the device hundreds, mabye 1000 times, per day. A great investment for anyone with 50+ hives.
Also, the customer care from Larry is top notch. He's always there to answer my questions and help me out with any issues that may arise.
