I'm on my second Vamo. The first just died suddenly after a couple of months of infrequent use (printed circuit board failed). I got another in July and it has been working fine. I put in a fresh charged battery tonight and it seemed weak. I checked the Voltage and it showed 3.6V. Put in 5 more batteries and they show full charge but as soon as I hit the Vamo power button a couple of times they instantly drop to 3.6 - 3.7V. I put them on the charger and the charger turns green within minutes but the battery displays the same problem.
I'm suspecting the Vamo is the cause considering I'm experiencing the same problem with 6 batteries. Fortunately I got both for about $40, from two different vendors, so I'm not out all that much but it's still unacceptable. I e-mailed the vendor but their return policy is 10 days so I'm probably just out of luck but I'll see how important customer satisfaction/return purchasing is with the vendor.
