I must first say that Jeff has been great through the entire purchasing process and providing information on the BK20 and providing the best equipment for our needs.
I have used the BK20 for three bed bug heat treatments so far and very satisfied. I recommend this product for anyone in the pest control industry to consider Prevsol equipment.
Thank you,
