Thank you. I look forward to your review.
That is the one I'm most inclined to get since it has the almost certainly best silicone gasket and the IMS seems to be a popular shower screen. Reviews look good and there is one mention of the "Pro" in a review.
Great Scale $11
WDT Tool $15
Gasket, Screen, Dispersion Block $50
