I purchased this item here. I am the third user, and I've used it for two months. First user: several months (Purchased new on Amazon in 2022, stored for two years) Second user: two months The manufacturing year sticker on the main unit has been removed. Also, the previous users have shipped the item with shipping labels directly on the box, so the box itself is not in the best condition, but the main unit itself is in excellent condition with no visible scratches. When shipping, I will cover the product box with plastic, but please be aware that it may tear during transit. I have lightly wrapped it with paper to make it slightly less visible. Please purchase only if you agree to the above. Thank you.
