Product review (5 stars): Quality product for a lower price than the Supco DSP1000
This is an awesome meter if you take a look at the Supco DSP1000 you can see it's the same meter under a different name. There are several products out there made in the same factory and just get different brands put on them. This appears to me to be one of them, a brand that I and many HVAC contractors Supco, and Flexzion which I don't know but appears to me to be the same product.

I already owned the Supco DSP1000 which I use for HVAC. I was able to get a great deal on this Flexzion and since it looked similar to the Supco I figured I would give it a shot as a backup if nothing else. Upon closer inspection it looks like a exact match. I put them side by side to test at several jobs and got matching results. The Supco is a quality meter but you can get equal quality for a much lower price.
