Review (3/5): Get what you pay for
IF I can get one that actually works (for more than 30 seconds) I may think differently but this unit quit working very soon after I started using it. I couldn't even get through one session without it quitting. I changed battery (twice) to be SURE because I need one of these, but ... no dice. I just processed a return and will follow up on the replacement if I get one that works (twice) LOL.
The unit was replaced and a free return shipping provided. All is well.
Late:: I received my replacement for this and FAST (two days). So far, so good. I will use it and if it fails again in short order, I'll return it. I appreciate Amazon and this vendor, for making purchasing (and returning) a no-brainer.
