New sled dollies never buy another set. I got ties of all the junk sled dollies on the market so I made some for me and a couple of extras if any one is interested. They are 75 a peace so a set of three is 225 but they are the best on the market.
nice design, your price is ridiculous. I think you could sell a lot at $100 a set, but $225 for three is hard to justify when there's some on the market for $35 a set.
I don't doubt yours are better made, but I'll bet my $35 set rolls just as well.
