      Disappointed customer

      Overall: 1 out of 5

      I am extremely disappointed in this product. There is no digital readout as to the frequenccy range AND......I left it on (accidently) overnight, and guess what? What? The LO BATT light was on, in the morning. (There should have been an automatic shutoff after a short interval, or an alarm tone should have been sounded. Sounds like it needs some re-engineering. If those two features were added, I might consider buying again!

      Also, the jacks on the face of this unit should have been spaced 3/4". It wont' take a standard molded plug. Disppointing. I would not recoomend this product to a friend.

      unforunate spacing of banana output jacks

      Overall: 3 out of 5

      I assumed that Tenma, being in the test equipment biz, would arrange the output jacks for use with dual banana jacks. NOT so. They could have made the case an inch longer, spaced the jacks correctly, and opened the door to easy connection to existing test setups(like mine) and adapters to BNC, etc. Sounds like an otherwise perfectly good unit, but I'll be returning this untried. If you are willing to manufacture all new adapters using individual banana jacks, I guess this is a good deal.
