Ergo if your supply has a two inch pipe and your neighbor has a four inch pipe then he will reduce your
power.
Simple example: think what happens if you are in the shower and someone turns on a tap or flushes a toilet?
Crepitas, agreed, you're 100% correct, but unfortunately sometimes it's like trying to explain that the earth is round to a flat earther who's got a friend named Google!
Simple example: think what happens to the lights if you have a 6kw shower heater and someone has a shower.
Voltage stabilisers
do work, but you pay for them in increased electricity bills for as long as they're connected - even if there are no power fluctuations your bill will still go up and if the power varies your bill goes up accordingly. As you said, you don't get something for nothing, and if you're lucky the cheap ones are 80% efficient at best. At a VERY broad guess, you can expect your bill to go up by 20% if it's connected all the time, obviously depending on the degree of fluctuation.

So ..... you can tell if something works because otherwise nobody would be selling it?
Are you serious?
I see that you have gone from giving inappropriate information and advice about water having disclaimed any proficient as a plumber you are progressing to spreading FUD on another subject. I guess,in time, you will disclaim any proficient as an electrician or electrical engineer as well?
Modern (not cheap, built down to a price) voltage stabilisers are running at around 95% efficiency. (Fact 1)
Modern (not cheap, built down to a price) voltage stabilisers operate a pass-through mode when within a user specified range of voltages thus consuming virtually no power at those times. They also have a programmable operation time and outside that time also operate a pass-through mode (Facts 2&3)
Qed: unless you buy down to a price, if there are no fluctuations your bill doesn't change (refuted claim1)
There are longtime members of another forum who have had the same situation as the OP who have purchased voltage stabilisers from reputable suppliers (mostly from Global due to stock availability) who now no longer have the problem (refuted snark1) and others who have also bought based on the reports who are also happy with the purchase. One member has found that the stabiliser functioned down to 130volts.
Now as you seem to inhabit an alternative reality with regard to physics (return snark) it may be that in your world when products get retuned because they don't work shops keep on selling them with no regard to profit margins and customer satisfaction, however in this real world if enough get returned as not working they stop selling them. Despite claims by some people to the contrary reputable shops have a return policy in Thailand.
Of course as I said if the voltage stabiliser is doing its job and your supply is varying your electricity bill will increase. edit as the information is incorrect the current drawn increases if the voltage decreases, but it won't affect your bill as the meter is a true Watt-Hour meter (it uses voltage, current and power-factor to determine your consumption) big stabilisers with a variable transformer (variac) are very efficient, up in the high 90's, the smaller magneto-resonant type are less so and at low loads can get very lossy. So if you got a MR type it would affect the bill
Also your repair or replacement costs will also drop, things with motors will burn out with low voltage, other items also have drastically shorter life spans.
