I've had mine for around 2 years now. I think whether or not they are worth the money depends on the user.

The high is definitely different, more of a head high than a couchlock high, no matter what the strain. It doesn't pack quite the same punch as a bong hit, but creeps up slower to what I find a really pleasant high. If you are a heavy user, you might want to look at either a more powerful vape, or maybe the power adapter extension for the MFLB.

Odourless? Not quite, but for all intents and purposes it doesn't get much better. The main smell will come from your bud itself, and the box itself if you leave it exposed for long periods during uses. If you pack these away after each use, the lingering smell will usually not be noticeable, depending on how well ventilated the space is. Even a little ventilation should be enough. Or like one spray from air freshner. So yeah, it can be odourless.

Another thing is what to do with the weed once you've vaped it. You can either smoke it in a bong, which for me gives me a slight body high, probably half as much for an equal amount of non-vaped bud, and no head high. Pretty good for desperate situations, recycled weed essentially. You can also gather a gram or so and eat it as is on a sandwich/soup, whatever you'd like. This is a real plus for the MFLB, doing this myself it takes a few hours to kick in, but once it does it is another 4 hours of an awesome high, followed by passing out every time. Good for a day off.

Other pluses are the portability - everything I need to use it fits in my wallet. Can still get very high from one trench so you don't necessarily need to carry extra bud either. Also the oil that gathers in your mouthpiece is pretty potent, can be harvested with a little effort. Stock batteries are good, I bought a couple slightly more powerful ones from amazon and can't complain about that at all. You can also vape concentrates like kief or oil in the MFLB with either the concentrate tray they sell, or just a piece of rolling paper. A kief trench will get anyone flying.

So it's great for stealth/portability. It has a lower impact than smoking weed, but for light users the high you'll get is still great, and with a little effort you can conserve a lot as you'll find vaping a trench goes a bit further than smoking a bowl.

If you're happy not getting quite so fucked, quite so fast, in favour of the stealth aspect, the MFLB is great. I paid about £80, and they all come with a lifetime warranty. Definitely worth the money imo.
