I bought this in December of 2013.  Until this week it worked perfectly.  I knew that it had a battery, but when I opened the battery compartment and removed the battery, a note on the battery said not to replace it.  This seemed odd, so I installed a CR2032 battery and it is working fine again.

Stopped working after the first time I used it. Changed out the batteries and all the wiring and it just doesnt work at all

It worked at first, but every once in awhile I would have to reset the codes because they stopped working. Now the codes will not work at all and it is not the batteries causing the issue.

My old one died in less than two years. Not the batteries. The whole pen died. I bought this as a replacement. Disappointing that tech dies in a couple years.

Upon delivery, I put batteries and and checked to make sure it worked, which it did. I just went to use it the other day and now it doesn't work. :( It won't turn on at all. Tried new batteries, still nothing. Cheap POS apparently.

This company has amazing customer service and offered to help troubleshoot the issues i was having with the product.  They obviously carry great pride for their product and will help their customers be completely satisfied.

On 06/02/17 I bought this radio Sangean DT-200 X fm-stereo / AM Audio Digital Tuning Personal receiver. It worked correctly the first few days, but for 2 weeks the batteries run out in 12 hours. I used the indicated batteries (2 AA size of 1.5 volts each). The first used were common Duracell, and now Duracell rechargeable. The truth is that I put the batteries, check that the charge indicator on the display indicates Full Charge, turn on the radio and work properly. I immediately turned it off, and after about 12 hours. WITHOUT TURNING ON RADIO, the battery charge indicator shows that theres no longer have power. It is as if the radio continued to consume battery despite being turned off. I have done several tests of batteries with different brands and the same thing always happens. In addition, I follow through with each step in the Instruction Manual. I request to inform me if this problem is due to some step that I have omitted, or that the radio is failed. Thank you

I bought it, it showed up, and it didn't work. I tried everything. I googled instructions to see if i was doing something wrong. Tried multiple batteries. Nothing.
