Review by Kari
Tilaamani tuote vastasi täysin tuotekuvausta ja takuuaika oli poikkeuksellisen pitkä: 3 vuotta. Tilauksen toimitusaika oli yllättävän nopea: 6 arkipäivää tilaksesta ja tilaamani tuote toimitettiin kotiovelleni saakka. Olen todella tyytyväinen. Ei mitään moitittevaa. Vaikka tilaukseni oli ulkomailta (Saksasta), niin se oli nopeampi, kuin kotimaassani tilaamieni toimitusaika. Ällistyttävää.
