Review on 🧊 8-Pack Silicone Ice Cube Trays with Round Ice Ball Molds - Black Ice Spheres Combo by Amanda Bonner

This article gives you exactly what you are looking for if you like round cubes. I should have realized that you would need to use something underneath for stability and that's not a big deal, what was a bit inconvenient is the small hole you fill each cube through. They are a "tiny" funnel that can be a bit tricky to use and keep on the tray. Also, if there were a couple of drain holes at the top that would drain the water if it overflows when filling that would be great, you can't tilt the tray to get rid of it as the cubes will drain too. which requires you to fill up, and the cycle begins again. The functionality is ok, the design could be a bit better, but I would buy it again if I need another one!
