AlpineReach Extra Heavy Duty Pot Feet Risers - 12 Pack Hexagon Plant Stand Supports with Adhesive Pads for Small & Large Flower Planters | Durable Outdoor Planter Elevators for Stability & Airflow | Perfect for Patio, Deck, Garden & Indoor Plant Protection

Very sturdy, not something that would blow or roll away in the wind. Works perfectly for lifting my flower pots on the cement and deck to stop staining from water sittingRAising planters so that plants can drain properlyI'm putting VERY heavy pots on these rubber risers and no issue after two weeks. Like them a lot!Some comments on the odor this product does release once you open the package... it will dissipate after a few days. I am utilizing this product outdoors, so not really an issue. They are holding up as expected for just over two weeks, but will see how they do over the hot summer into the cooler months. Very easy to pop under the pots... and I did not use the stickers to keep in place. (don't see that being effective).Pros - the product does not take away from the look of your pot. They can be placed in a way that really keeps them out of view. (Hint. If you have larger pots... estimate 4 "feet" to give a nice sturdy pot. ) I had my pots up on small pavers to allow water and air under the pot, but they just did not look appealing. This does a great job of sitting under the pot.Cons - none so far... but curious to see how much they hold up after a year in the elements... between watering, summer heat, and cool fall temps...Hope that helps...Worked perfectly for the intended purpose. As others mentioned, there is an odor, but I am using these outside and the odor disappeared quickly.Mine did not smell bad as others posted.Odor was not overpowering as I feared from other reviews. Used them in my home and no odor after initial opening. Adhesive holds and they’re very sturdy.They’re sturdy, light, easy to apply. Should come with as an and a bit of sand paper. Instructions should say to do while pot is empty and upside down.
