I saw a GLV-2 5v for sale in the classifieds and the seller stated that it gets warm and needs to be repaired. So... is the GLV not supposed to get warm while using it? I'm using the batteries I bought from Jay and have a Cisco LR 1.5 atty on it right now. Yes the batteries are in the correct way. The end caps get hot and the tube gets a little warm. Just thought I'd check in with other users to see if this is normal. I didn't think much about it until I saw the one for sale. Maybe ignorance is bliss?
