BlendJet 2: BUYER BEWARE! Purple ring of death...

Please know that these BlendJet portable blenders don't last long. They claim to be waterproof, but I'm pretty sure mine stopped working because the charging port corroded after repeated washing. I never submerged it, and washed it as instructed, yet after only three months, it simply refused to charge. At first, it would give me just a pulsating purple ring that would stay that way for hours. Yes, I checked (many times) to make sure it wasn't locked. Eventually, the pulsating purple ring crapped out as well. Every time I plug the blender in now, I'm greeted with no light whatsoever. It's basically dead. Remembering I had bought another BlendJet for a friend of mine, I opened it up to find it didn't work at all. I plugged it in and fully charged it, yet when I attempted to use it, the blender told me the battery was dead, even though I'd just charged it. Yes, the arrows were perfectly aligned. I plugged it back in and, to my dismay, was greeted by yet another pulsating purple ring. I went through the motions again, checking several times to make sure it wasn't locked, yet every time I plugged it in, I'd get the same pulsating purple light. It just refuses to charge and is therefore completely useless. To reiterate and clarify, I checked many times to make sure both blenders were unlocked. Yes, the arrows on the blender base and blender cup were aligned every time on both units. I even left both units plugged in for over a day, yet they still didn't charge. Basically, one crapped out after just three months while the other never worked to begin with. I now have two $45.00 paperweights because the second one, which didn't work fresh out of the box, was beyond its return period. That's $90.00 wasted because these things are just cheap crap. Save your money and go with a different brand.
