    couldn’t be more impressed! I purchased the Canon EF 24-70mm f/2.8L II lens and needed it urgently before my trip. The seller went above and beyond by arranging FedEx Express shipping to ensure it arrived in just two days—from East Coast to West Coast! Communication was fast, clear, and professional. The item arrived exactly as described, perfectly packaged, and in excellent condition. Truly one of the best experiences I’ve had on eBay. Highly recommend this seller—thank you again for your excep

    Shipping was quick and the item was packed appropriately. Cartridge came in great condition and as described. Wouldn’t have gotten this game much cheaper elsewhere.

    This calculator adds up for value!

    For the price, this was a good value. Some of the buttons are sticky but still registers the buttons
