Mine didn't last long  Time owned: 0 to 3 months
I bought one of these meters just as RS was closing them out; think I paid around $40.00 for it new. It was the first and only digital meter I've used, and I liked the small size with easy to read numerals. Sad part is, the power reading circuit failed after only a few months use. The auto-SWR circuit continued to function. I eventually bought another meter, not a RS model, but a SWR/Power meter that used the normal analog scale.
I see these meters being sold on eBay, and I am amazed to see people bidding up to $100.00 for this meter! I never had another meter such as a Bird to make comparisons, so I cannot say how accurate the meter is.

A Choice Must Have Unit!  Time owned: 6 to 12 months
I liked mine so well I bought a second one for the car/portable operation.
Yes it reads from .5 watts to 2000 watts
Yes it is automatic ranging
Yes it is auto zeroing for immediate SWR readout
Yes it is accurate
Yes it is great for QRP operation.
Yes it takes 12 volts off a battery or supply
Yes it has a PEP meter that in the Peak position holds long enough to see a reading in SSB mode with a quick whistle or with the processor on. Some think it is too short but I beg to differ.
Yes it is attractive and display is nice and large.
A good overall value and attractively styled.
The auto zero SWR is great and power meter reads out in numbers and on a auto 0-200 scale simultaneously. What could be better for the price....used around $40-50. If I like it you will also.

Good Value!!  Time owned: more than 12 months
I've had mine for about 6 years. I use it everyday and have never had a problem with it. It is very easy to set up and appears to be reasonably accurate. It consistently matches the Power Meter on my MFJ-989C tuner. In addition I know what my radio and amplifiers can put out as far as power so I can say for sure this meter is reasonably accurate.

You can buy a better Power/SWR meter but for what mine costs me I feel I got a very good value. Unfortunately this item has been discontinued by Radio Shack and you would have to look in the used market for one.
