I am now ahead financially, having saved on two mat replacements, and that looks set to continue. Perfect rolling action, zero problems--this is a top-class product.I was ready to change my rating to five stars if the seller had updated their FAQ page to address the issues expressed here over the years. But no, they haven't--so I haven't. Great product let down by inattentive seller.Original review September 2011:Installed these yesterday after my chair mat almost succeeded in stabbing me with another broken shard of hard plastic. Fine casters so far, moving well on standard office carpet.I deducted a star after experiencing installation problems, and not finding a scrap of help on the seller's website. Seller, you already have a questions page, I recommend you include answers to some of the questions or issues raised in these reviews.First caster installed fine with strong hand pressure--as did the fourth, later. Second didn't, but eventually went in with some light tapping from a small hammer. However, this didn't work with the third [or fifth] caster, and I wasn't about to start any serious hammering. I tried different casters on different chair legs, in case it might be an issue of two maximum machining tolerances causing a failure.Getting the first two casters in suggested it wasn't the main caster stem which was the issue, and led me to quickly identify the problem as badly shaped metal rings in the groove at the head of the caster stem--they were jutting out too far beyond the diamater of the stem. They are very strong rings, I couldn't squeeze them smaller with a needle-nose pliers.I went with the easier solution of prying off the problem rings, and then using the rings from the old casters in their place. These other rings were a little more flexible, I was able to shape them with the pliers both to open [to get them on the stem] and finally close them a little. Miracle Casters popped in fine after doing this.The function of the rings seems to be to hold the casters in the chair leg, without one the caster was totally free to slide on and off the leg. I'm only guessing that you could use the casters just fine without the rings, but they'd fall off if you lifted the chair--not too big an occasional deal for most people, probably.Fyi, I'm using these casters withΒ  Alera Ravino Big & Tall Series High-Back Swivel/Tilt Leather Chair, Black , they might be overkill with smaller less sturdy chairs, especially ones without metal legs. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars First impression after a weeks use, absolutely awesome on carpet *by R***N on Reviewed in the United States on September 22, 2022* These are everything claimed, Worth the price even with shipping to NZThese work supurbly on my desk rug on carpet. They're very gentle on both with their large surface area, roll easily and raise the chair base nicely offering lots of clearence for my old hanging out the bottom cylinder which was previously catching on the rugPurchased to replace office oasis blade, which were purchased to replace stock Aeron carpet castors. The blade style castors helped things one way by lifting the base, but crushed, and mangled the rug badly due to their small contact surface area. The Miracle castors are really comfortable, and feel very solid so far. They are biigg and make the chair somehow look more imposing.. but I like that too ### ⭐⭐⭐⭐ 4.0 out of 5 stars Chair is easy to roll on carpet now. *by K***I on Reviewed in the United States on November 25, 2022* Castors are big and sturdy. They were easy to install and do make my chair easier to roll on carpet. The only thing I do not like is that I sit a little to high now even on the chair’s lowest setting because I am only 5’3. ## Frequently Bought Together - Miracle Caster!
