"I use this hood five times a week. We have not had any problems what so ever. We also have four other hoods in our operation, all different brands, and this is by far one of our best."

"We are greatly satisfied with this product! Not only did it ship in great time, but the quality is fantastic. After shipping I simply removed it from the box and it was practically ready to use. The UV light works great and I love the easy to use built in pipette holder in the back! I haven't had any cross over contamination while working with PCR assays since I purchased this product."

"This piece of equipment is a must have for all labs that use chemical processing for latent prints. Processed a note from a notebook from a homicide scene and had identifiable latent impressions on the paper. This unit has taken our division to a whole new level. The machine is very easy to operate and produces high quality results. The machine is sized right and is great value for money."

"I have purchased 5 PTEFH-72 Exhaust fume hoods from Air Science and have been 100% satisfied. One of my purchases had a damaged shelf and I was rushed a replacement. I have dealt with Devon Kramer on numerous occasions, and my customer service was better than I have had in a very long time. If you are looking for top notch product and excellent service, these guys cannot be beat. I order a lot of equipment for my shop and when I was sent an invitation to review this company I jumped at it. Big thanks for making buying a better experience."
