It seems the loss of the Batteroo is way more than what you'd expect based on efficiency alone.
Why do you say the losses are more than expected? It seems just as expected to me.
- The inefficiency of the converter itself is going to waste a huge amount of power while doing the boosting.
- The power delivered to most loads is going to be at its highest for the whole time it runs because of the constant 1.5v supplied to it, using far more power than it normally would with plain cells.
- Each cell itself is going to be discharged at a much faster rate because of these factors, leading to significantly reduced total cell life.
The sleeve might be beneficial on something like a travel electric shaver (Remington 2xAA) for instance, where performance is more important than longevity.

You may say that now until you have your trimmer die half way through, leaving you with a half trimmed face... I'm going to have to say I'd rather have the warning sign of the motor slowing down.
These points have merit but without data to back them up they are just speculation.
It needs some serious testing to see what the exact cause of the poor efficiency is so it can be determined what kind of loads would benefit from the Batteroo sleeve and which don't.

Does this Batteriser continue to use power to regulate the output voltage when the device is switched off?
If so, wouldn't this make is useless as it drains the battery continuously?

Good point, I bet the batterizer designers never considered radio interference. I wonder if it has FCC approvals...
Yes, a FFC test was done, with a 1 kOhm resistor:

I've done a test with a 1 kOhm resistor as well, but only for the output voltage, and ripple was 200 mV:

So EMI might be no problem, but the high ripple, which EcProjects noticed, too in his videos.

I await the full, proper, performance characteristic information which Batteroo promised about a year ago....
The fact that we are having to do their testing for them, well...

That is a massive difference and I'm curious to figure out where the energy went. Maybe that knowledge comes in handy one day when designing a battery powered product.

How about if I create a battery powered hand warmer to place inside my gloves, battery included...
All losses introduced by the batteriser are given off as heat, and since I'm powering a resistor with mechanical thermal switch as the heating element to generate the heat, there should be a net 0 loss. The batteriser basically adds the regulated switching supply my resistor heater circuit is missing improving the design. This means with my resistor heater element tuned to warm my hands down to -20 deg.C. As the battery drains, it will only partially warm my hands without the batteriser. (Yes, I know the hand warmer will drop dead at 1 point with the batteriser, but, all known inefficiencies due to the voltage step up converter is given off as useful heat to my hand since the battery is in my gloves as well...)
Have I earned your 10$?
That is a massive difference and I'm curious to figure out where the energy went. Maybe that knowledge comes in handy one day when designing a battery powered product.The train has speed regulation.
I doubt that because it would increase the price without any purpose. I just checked the video again and the train runs faster with the Batteroo so if the train has any kind of speed regulation it works poorly.

It doesn't have electronic speed regulation, just the way the motor is made mechanically makes it want to operate towards a certain RPM range...
The question then should probably turn to legal remedies. They are making money off of fraud. IANAL, but the US does have lemon laws that might form the basis of a backlash against this, and I'm sure other countries will have similar consumer protection laws. They've probably never been used against a crowdfunding campaign, but everything's got to start somewhere. If this was a high-profile enough campaign it might be a good test case. That might depend on whether crowdfunding backers are considered "consumers" or "investors" though. I believe there are less protections for investors, which would provide way too huge of a loophole for these slimy bastards to ooze through.

It's also a function of the reduction gearbox, with the motor turning at high rpm and the train moving very slowly.

...I would bet the motor is designed to be optimal somewhere around 1.3-1.0V as it is the most typical range for battery. So when we feed it 1.5 constantly it does go faster but it's way less efficient, which result in very fast discharge. I do not believe the loses in batteroo itself can explain such a drastically poor performance.
