The best one on the market

I actually think this hood is the best one out there. Some cool innovations in terms of backflow prevention, lightweight, and the option of getting the NIST cal in case you don't need it then you don't have to pay for it. Also lots of fabric sizes for different grilles are available. The standard 2 by 2 works fine for me but you can pick them up and pop them on as an when. Great stuff from Testo

Great hood and best price

So there's a famous brand that designs these flow hoods that most peopel use in TAB work. TEsto is the direct competitor now and having used both I can tell you they are comparable. This one is jsut as good and much less expensive. You're paying for the brand name if you buy the other one and Testo itself is a reliable brand so I don't see any reason why this wouldn't be your go to for a flow hood. Highly receommended.

Great analyzer

This is a great little analyzer. It is a basic analyzer with new extra bells and whistles, but it does pretty much everything I need for residential and light commercial applications. It responds to changes in combustion much more quickly than any other analyzer I have ever used. The only drawback I have seen so far is that the hose leading to the probe is a bit shorter than I am used to and fairly stiff.

another great testo product

I was not too surprised that testo has finally released a balometer but i wonder what took them so long. I have a lot of testo products and i am just as happy with this as my others. They really understand what us technicians need.
