Charging Lithium Ion batteries

Although Lithium Ion batteries are increasingly popular, there can be a lack of clarity when it comes to the charging process. This is not a problem with Mastervolt as the Mastervolt battery chargers communicate directly with the Lithium Ion battery via the integrated MasterBus (or have been adapted to the required charging voltages).

MasterBus compatible

Mass battery chargers can be easily connected to a MasterBus network with only one cable and one connection. You can also choose central, local, or remote monitoring, configuration, and control of your system.

Not good if you need Whole Foods gift cards
If you want to buy Whole Foods gift cards (which is why I got it) it flags it for fraud and doesnt let you. I was told you can spend at Whole Foods but not buy WF gift cards, even though it is a Prime Credit Card. Also if you buy WF gift cards online, you dont get the rewards since its from a gift card company and not Whole Foods.

The Christmas movie no TV stations ever seem to show during the holidays
Since Amazon lumps the reviews for all the various releases of this movie together, I want to be clear that this review is for the single disc, 132 minute blu-ray version with the cover picture of smiling man made of bricks with the word "Brazil" flying out of the top of his head. For those who don't know the history of this movie - there are at least three different versions. It was originally released in Europe as a nearly two and half hour long film. The studio who financed it didn't like that version because it A. was too long, B. was too uncommercial and C. had a dark, depressing ending. The contract they had with Gilliam stipulated that the movie had to be less than 2 hours and 15 minutes, so it could have multiple prime-time showings in theaters. They suggested he cut the ending. Gilliam refused, so the studio took it upon themselves to create the "Love Conquers All" version, which chopped out almost an hour of footage - they only kept the parts that showed the main character Sam in a heroic light, anything that contributed to the Sam/Jill love story and anything that featured Robert DiNero. And, of course, the ending was changed to a happy ending by removing the final scene. Also, to make the plot easier to follow, they used some alternate takes, some deleted footage and hired voice actors to overdub dialog. Unsurprisingly, Gilliam didn't want that version released, so he finally edited the movie down to 2 hours and 12 minutes, kept the dark ending and made a few other minor changes and the studio was contractually obligated to release that version to theaters in the United States. It's this US version that appears on the blu-ray, with absolutely no additional features (not even the Gilliam commentary that's included on most other releases of the film). Annoyingly, they also added advertisements for other movies to the main menu screen. But I'm still happy to have this version, because it's the first time I've seen the "US edit" since originally seeing the film in a theater on the campus of Penn State back in my college days. I can't really write an unbiased review of the movie itself, because from that first viewing I became obsessed with both Brazil and Terry Gilliam's films in general. I bought all his movies on VHS as soon as they came out and eventually replaced them with DVDs. I bought the 3-DVD Criterion "Final Cut" version of Brazil back when it was an expensive new release. I was surprised that it included scenes I'd never seen before - I think it's based mostly on the European version, with some additional tweaks by Gilliam. It also included the "Love Conquers All" version of the movie and a ton of bonus features. Sadly though, it wasn't animorphic, so on my widescreen TV it put black letterboxing bars on all four sides, shrinking the picture down to about 60% of the screen. This blu-ray was exactly what I was looking for. While it's missing a few (non-essential) scenes, it's the version of the movie that I "grew up" with and is presented in full 16X9 animorphic widescreen. It's the best looking version I've seen since originally seeing it in the theater. For example, I never really noticed the makeup on Katherine Hellmond at the beginning of the movie to make her look older (pre-surgery), but it's clearly visible on the blu-ray. I've always felt bad for one actress during the explosion scene in the restaurant because it looks like she really does get hit by some of the flying debris - the blu-ray is maybe a little too clear there, because now I can tell it's just a dressed-up mannequin. As for the movie itself - it's one of those films you'll either love or hate. Its alternate-reality, retro-futuristic look makes it seem nearly as fresh and amazing today as it did when it first came out. And the background plot of a government bureaucracy turning a country into a surveillance state in response to a perceived terrorist threat - I know it was based on things happening in England at the time, but it's like Gilliam had a crystal ball and looked 30 years into the United States' future. The alternating between "reality" and dream sequences and the general Gilliam quirkiness will probably put a lot of people off, but it's what drew me to this movie in the first place. If you become fanatical about the movie like I am, you'll need both this blu-ray and the Criterion release. To fully experience the film you need to see every version (even the Love Conquers All version) because each one includes bits that aren't in any of the others. If you do decide to watch Brazil and find that you like it, give some of Gilliam's more recent movies a try, like The Imaginarium of Dr. Parnassis and The Zero Theorem. Really, if you like odd, out-of-the-mainstream movies that you'll be thinking about for days after you see them, you can't go wrong with pretty much any Terry Gilliam film.
