i purchased a genuine nano vna first, and then i purchased this unit apart from having a smaller screen, it is readable even for an old guy like me that has had one cataract done and a detached vitreous with big floaters i see a lot of folks griping about its small screen, but in my mind it is one heck of a value but then again i remember back in the 70's you couldn't get close to a spectrum analyzer for less than a few tens of thousands of dollars, and you sure didn't pack it out into the field in your shirt pocket. is is perfect, no! but like the nano vna it is close enough to being so for the girls i run with. between the two unit, the nano and the tiny sa, i think they are far and away the best money i ever spent on test equipment by a long stretch. i highly recommend both for ham's that like to or want to build antennas and be able to accurately test how well their designs work. lastly, lest i forget for those that want a bigger screen, both units can be attached via a usb cable to a laptop for not only a larger screen but expanded capabilities. so pack the tiny sa around with a netbook or a tablet and you got a really useful setup Read full review

Disatvantages: * it has a large noise figure without an external amplifier * it offers a few resolution bandwith to select * no video bandwidth or averaging feature, so changing signal level measurement is difficult Nevertheless, it is a handy, easy to use device for this price.

This works very good if you keep signal below -30db. No it is not a HP but for the price it's great. I bought mine to learn how to use a real one without spending big $$. I also like the external antenna and portability of the unit. You can't put a HP in your pocket can you?

An excellent addition to my electronic tools. During experimental work I can leave it on all day with the power connected and reserve the battery power for portable use at any time. Nicely built and very good accessories come with the instrument.
