I ignored the reviews because I had such high hopes for a easier way to wick my vessels. I use the CS straight sided tumbler, and like many of the reviews says, it does it not fit. The size range is supposed to be between 3-3.75 or so. As soon as it’s placed in the vessel, immediately, you noticed it’s neither leveled or evenly placed. You find yourself positioning the device over and over, and attempting to center it to get the wicks placed in the middle & at that point, is it worth it? From what I received, it’s poorly made. The product doesn’t reflect the dollar amount. The white handles continued to fall off & that’s the least of this device’s issues. The instructions given are terrible. Usually with any type of device or equipment that you have to put together, it shows drawn pictures illustrating the names for the items they’re telling you to use. The instructions which are shown above in the template just give you a step 1-3 type of model with no indication on what is what. I was able to put it together from looking ahead the photo. Overall, I should’ve listened to the reviews. Will be returning.
