I use fan jets on fsg cleans and have never broken one yet.
As for problematic seals, if they are really bad, bye bye custy.

i use fans for upvc ive gor the gardners ones they have never snaped i just find then not good for windows as there not accurate anough for me 80% of my round has bad rubbers lol

Water that drips off seals after you clean isn't because you use fan jets, it's because you use water. 

not seals m8 i mean the top rubber on the glass if water tuches it it then leves a run down the glass ,when i use pencles i turn water off swipe off the water and the water droplets off the top rubber then rince just below it as close as i can with out tuching it ,but with fans i cant do this as they spray back on it lol

Not sure what you mean.
The top rubber on glass is the seal.
Sometimes they can drip muck or oven black marks. After a chemical clean, they are usually ok after.
If they are old, they can leave a small gap for much to sit under

Lost count of how many of the Gardiner ones I have broke - the barbs snap off easily ( I'm sure colder weather makes the plastic brittle ) .....a sub standard product IMO.........If you want more robust and more powerful ones that actually last then buy lumark  jets instead, they have a metal body and barb with only the fan part plastic that protrudes from the brush same as gardiners ones.

Since changing to lumark blue fan jets I have been happier with them and have lasted two years with no problem.
This isn't really a thread about whether fans are better than pencils - I use both as both have their specific uses.

there was a test on fan jets a wile back on fb gardners vs turbo jets vs xline jets and the xline jets came out on top  for power of rince!

Jets don't create the power, it's the pump, it's pressure rating, its output and hose diameter that determines what force the water comes out at.
