I recently bought my 6th NEBO LED light, the smaller ones (AA cells) for the nightstand, car, etc. ALL of them have had problems such as the red won't work, the white light won't stay on, or the light won't turn on at all. I sent one back to the company at my expense and they said they've had problems and sent me a new one. That eventually quit too. I asked them again to repair/send me a new one and they said sure but it's on my dime. I have two questions: Has anyone else had such issues and what reliable company making these LED lights? Thank you!
