I purchased this about two weeks ago and have only used it for about three days, so I think it's still in good condition! The logo sticker has been removed. The magnetic force was sufficient, but I plan to use something else, so I'm selling this. Returns and refunds are not possible due to reasons such as feeling the magnetic force is weak after purchase. I have disinfected it with alcohol and stored it, but please refrain from purchasing if you are concerned about minor scratches, etc. Thank you.
