Review: 後で判明したがアマゾンとその他で1000円近く値段が違う。類似の商品にも出て来なかった。 ２４時間装着とあったので着けて寝たら、かぶれでしまった。本商品とは素材が違うが、高いので怖くて買えない
Review: この商品は詐欺のようなものです。絶対に購入しないでください！価格が高すぎるうえに、説明にあるようなdesertcartのクレジットも一切もらえません。リング購入時のクレジットを期待して買いましたが、何も得られませんでした。完全にお金の無駄です。日本ではビックカメラやヨドバシカメラで無料のリングサイズ測定サービスがありますので、そちらを利用した方が良いです。この商品にはお金を使わないでください。 This product is a scam — avoid it! It’s completely overpriced and does not give you desertcart credit as advertised. I bought it expecting to receive credit toward my ring purchase but was unable to. Total waste of money. You can just go to a store for free sizing — in Japan, Bic Camera and Yodobashi Camera both offer ring sizing services for free. Don’t waste your money on this product.
