Great value, reliable.  Time owned: more than 12 months
In 2005 I decided I needed a calibrated generator that could be used to align and measure the performance of vacuum tube general cover receivers. For the money, nothing else even came close to the URM-25D. It's wide frequency coverage and easily controlled amplitude down to .1 uV was simply too good a deal to pass up.
I got mine rebuilt from Ashley Hall (KISS Electronics) and have not had one moment of trouble. Everything has worked as it should from day one. When fully warmed up drift is usually a very manageable +/_ 5 ppm per hour. Shortly after I started using it I discovered it made a great marker generator for finding the frequency of SW stations. It has been left turned on and used daily for the last 6 years. No problems.
