been using what i bought for a couple of weeks.
I've got to say they are better than the times I have used them in the past when bought from other companies.
I think they are' fresher'. The sod/met' smells massively more pungent and I believe is more effective and the sodium perc' is a lot more active when mixed, you can see it reacting in the sprayer and again I think it is more effective.
either they are fresher, ( I don;t know if these chemicals become less effective as they age) or they are more pure but I can see a difference.
they turned out not to be any cheaper than any where else because I only bought small amounts but if a group got together and bought it in big quantities then they are very cheap.
