Review on Secure, Waterproof, And Versatile: AROIC Heavy Duty Adhesive Hooks – 40-Pack by Michael Nastanovich

We are using the suction cups to hang a tarp skirt around our camper. We full time in the camper so they will remain there through the winter. We placed the suction cups on a smooth-ish surface along the bottom on a 50 degree day. I was worried about the surface not being completely smooth like metal or glass. The front side was getting full sun so the material and the suction cups were warm. The back side was shaded so it was cooler. At first we did have some falling off mostly in the back. I cleaned the cup and the surface with alcohol and used a heat gun to warm both up. We have had a couple weeks with night time temperatures below 20, wind over 20 mph gusts, rain, and a little snow. The suction cups are holding strong. I haven’t had to re apply them in over 2 weeks. Occasionally one might pop off but I am extremely satisfied with how they are performing. If they can handle the task I have put them to, I can’t imagine having any issues in a more normal application especially indoors. The only slight issue I had was the hook was too large to fit all the way into the grommets on the tarp so I had to grind them down a bit on the sides. If you are hesitant go ahead and give them a try. I took a leap of faith buying 5 bags at one time and I am a satisfied customer!
