Powersaver - Does it work?

I came across this website:

I was wondering if anyone can tell me if these devices would work?
The techie bit says:

Electrical flow is not stable. It contains small power spikes which can not be used by your appliances.

These spikes 'leak' usable electricity from your circuit and get converted to heat inside your electrical wires which can damage your appliances over time.

Our PowerSaver 9 uses a system of capacitors and patented components to smooth out these power spikes which increases the power factor in your circuits
I wasn't aware that my electricty would have unusable spikes that I was paying for but not using? Is it all nonsense and this was too good to be true?

Wow 40% saving on my electric bill!!

No complete nonsense from a money saving aspect.

Covered lots of times, on this and other forums.

Essentially any Power factor correction device has no effect on your bills as it doesn't matter on domestic electric meters what Power factor you have.

Ok thanks for that. Not being too techie on this and I wasn't certain that this was a "Power Factor correction device". I can only assume therefore that it is.
