This product we used a lot of last year and seems to be on top of the job but, it needs a good vigorous shake as it settles into different layers a bit like paint with oil at the top and also I found the container itself needs improving to give it a good thorough clean out as its easy to leave residues in it which is far from ideal. Also an improvement in the box packaging to put holes in the sides to help carry the box wouldnt go amiss. Overall a good product but room for improvement in important areas.
