I like it very much, Bea, and in fact I have two Freds. There are some minor issues with it tho, and tho they're not a big deal, it's good to be aware of them upfront. Both the battery cover and the 510 are, ummm, odd. The batt cover has a little pull tab, which can be tricky to actually hang on to. Also the threads, and primarily on the red one, are very thin and take some time to work themselves in, making the cap a little hard to open/close. I found the way to do it after a very short time, and now it's a piece of cake. The top 510 has two holes that allow for tightening/loosening/cleaning. Odd, but really no big deal.
Echoing DPL, in the price range, and if you like it, and if it were one or the other, I'd JUMP on Jackie OH! The two mods are worlds apart, but run along the same money stream. The build (form and function) on the Jac is tres suite, and miles above the Fred. Sorry, no red Jackies.
