I bought six of these metal, magnetic, spice tins in 2016. I have thoroughly enjoyed them! I keep my less used spices in the cabinet. However, I wanted quick access to my most used spices, while cooking. I keep mine on the stove. However, the magnetic base covers the entire bottom and is quite strong. So, they'll securely stick anywhere...With that said, I use mine daily and have simply worn them out! A couple of the closure covers are lose and I finally broke the cover on one end. The lids and tins themselves are still in perfect condition. However, after thousands of openings/closures, the plastic finally gave way. I did not expect these to last a lifetime. And I'm very surprised they've endured daily use for over 8 years. I could easily use them without the cover, but since they're exposed on the stove, I prefer them covered. I would definitely recommend these, as I am ordering myself another set.I've included pictures to better show all 3 pieces of the shaker and how they fit together. As you would others, I suggest periodically cleaning them for optimal function and to prevent buildup, esp when used over steaming meals.Note: I read a comment that the lid would not close after filling and it fell off during use. This has never happened to me. The metal tin has a small lip at the top, ensuring a tight and secure fit. You can hear a click, when the lid is pressed down completely. Unless the lid was faulty, I can only see this happening if it were overfilled or not pressed down completely.Also, there was a comment that the spout cover would not close. In my 8 years of experience, this only happens if there's an accumulation around the pour/shaker spout. The other possibility could be if the cover was used to pull off the lid vs grabbing the lid itself. (Which I did once) Since it takes a good tug to get the lid off, if the cover was pulled, esp at the wrong angle, it could have damaged or stretched the plastic. Otherwise, they have been extremely durable and have well outlasted my expectations.
