      Great little scope-meter!

      Overall: 4.5 out of 5

      Originally purchased one of these for work. Everyone who used it thought it was great so we purchased a couple more of them for our guys to use in the field. So far I've heard only positive comments and no complaints. These are especially nice for travel, particularly if you're flying since the case is compact and everything fits inside without hiding anything else. It's pretty easy for TSA to see that it's a legitimate piece of equipment when you just open up the case (no need to empty everything out like they typically make you do with scopes in soft bags with pouches for the accessories). It's only a 20MHz scope but that's usually sufficient for our work, especially for field service of our equipment. I like these units well enough that I recently decided to purchase one of these for myself when they were on sale at a discount. My only complaint about the equipment is that the wall supply that shipped with these originally has been replaced by a desk supply so now a somewhat bulky AC power cord needs to be shoehorned into the carry case. Since the case was not designed to accommodate that cord it's kind of a pain to get everything to fit. I do wish they'd go back to the wall supply so all accessories would easily fit into the case. One other beef is the manual - it's really poorly written (or poorly translated at least). Obviously, this isn't particularly surprising for a bargain priced piece of equipment from China but it's still something to consider. In spite of the power cord and manual I still think this unit is an excellent value.

      I wish I had purchased this scope two years ago! I have been trying to justify a handheld scope for years but just could never see spending for a Fluke - then I ran across this. Needless to say, I am sold! Great product and great features as well.
