The video was to put your comments into perspective.
+-£22 is more than a third cheaper than what you are plugging. Pan the Organiser couldn't make a real choice between any, from the cheapest to the most expensive...........go figure
I didn't say you
had to spend £35 to have a worthwhile cannon, I was merely recommending the £35 cannon that was already suggested. If you want to save £13

then that's your prerogative, but as the saying goes "you get what you pay for".
I must admit your £17 cannon does look a better quality item with it's brass neck than the £10 plastic cannon you suggested Ant should buy.
How do you know the £10-00 units do not work? Are they the same as the unit you had?
I do not know if they are all the same but as I mentioned, I wouldn't buy another cheap £10 plastic cannon, the one I had was useless. I wouldn't recommend an item so cheap with a plastic neck. My statement was all about
my recommendation.
Your implication is that more expensive units are better.
Maybe ask the 1000's of professional detailers around the country/world, do they use £10 (or £17) snow foam cannons. Or you could continue to be blinkered by your man Pan.
As stated, I have a £17-00 unit that works perfectly well so why pay £35? The snow foam mixers / cannons/ lances are very simple bits of kit and like all fads the sellers are climbing on the bandwagon and charging exorbitant prices.
My original comment had nothing to do with your £17 cannon, I only compared your suggested £10 cannon against the £35 cannon that I have experience with. If your cannon is suitable, why didn't you recommend that to Ant instead of a £10 item?
Although I don't think it's a good idea to throw money away, it sounds like every penny is a prisoner with you so you should continue the way you feel best. p.s. I'm not sure where you will be able to buy an egg cup full of snow foam to perform your test.
If you want to continue to dismiss other peoples recommendations and experiences on this subject then that is entirely up to you.
