High quality as description and pictures. Highly recommended.
But you have to be patient because it take too long time to read or mature.
really bad experience with this Seller. the product no is not good. firts i received the item and doesnt works after the Seller sent my one replacement.when i received It i calibrated again . i calibrated it with the two buffer (ph 4 and ph 6,86) and i test It after, i could see that this equitment gives bad measures. and if you have this problem the Seller says: It is ok!! so you open a dispute and show proof about the bad working if this equitment and how th e seller prefer Jeep the money, you ll lose your money un the dispute. dont trust about the item or this Seller because also the seller doesnt know how It works. i dont recommend treat with this seller and buy this item DONT BUY THIS EQUITMENT!!! el equipo funciona fatal , después de una parte rota remplazo calibración da medidas erróneas. si abres disputas y enseñas pruebas pierdes el dinero con este vendedor. no recomiendo el producto ni el vendedor que no tiene idea ni como funciona un phmetro. NO COMPREN ESTE PRODUCTO!!!
