whilst the product has done the job as expected , I have a gripe about the delivery charge, namely that it was sent in a box approx 6x4x4ins, when a small jiffy bag would have done the job and the p&p charge would have been a lot less
Too early to assess its efficacy but certainly looks and handles the same as other, more expensive (some considerably so) vermiculite that I have used.
Held ducting in place worked very well, good price too
