Thank you for viewing. I purchased this in 2019 and used it intermittently, though not every day, for about two years. I believe I maintained it to a reasonable extent, regularly applying silicone spray to the cylinder. Please understand that this is a used item, and refrain from purchasing if you are overly concerned about its condition. I will gradually lower the price, so please consider it.
