I have 6 of the older Reos - 2 Minis, 1 Grand, 2 Grand Woodvilles, and 1 of the first wood Grands. They have all given me excellent service over the last three plus years. I just received the VV Grand & one of the new RBAs. I used Rob's video to build my first wick (took about two minutes), tested it at 1.6 oms, charged the batteries, fired it up, and I can't believe the vapor & taste that it puts out. Much better than all of my other Reos using LR510 attys. I'm completely sold on the new set up & will now have to purchase another VV Grand so I always have a spare. I also bought a 2nd rba, and a lot of various wick material, wire, and ribbon wire so I can try all of the great wick ideas I've found here on the forum. Thanks Rob & all of you posters here on the forum!
