I just got my Grit Guard Washboard today and tried it out while washing my 1999 Chevy K2500 and 2016 Mazda 6. This thing is totally worth the money. It is so much easier to scrub the wash pad on than the Grit Guard at the bottom. It seems to be sturdy and attaches securely to the Grit Guard in the bottom of the bucket. The only downside it is that I can't stack my buckets with the Washboard in place, but that's a small price to pay for such a handy tool.
