It does what it says! I placed a heavy pot on wooden decking and am able to move it without any effort. Great quality. Best on the market. Its not cheap but like anything, you get what you pay for.
Low profile and looks really good (no exposed wheels). Very robust and moves pots across the deck and paved areas easily. Have bought 5 of these now so would recommend!
My Omnia Gliders are certainly making my larger pots easier to move (on my deck as well as on tiles). They are not cheap, and so I hope they last for the guarantee period (3 years, I think) and beyond. If they do, then happy days :-)
