This store is very good at product authenticity and shipping. I have recently purchased a Casio fx 991 ex-calculator and a G-shock watch from this website. The shipping was done through Bluedart logistics and they arrived in 3 days post my order date. The packing was great as expected from Bluedart. Both of the items are genuine and properly sealed. The prices are also on point with the services. I found the calculator to be cheaper than any other website. Also, they have a wide variety of Casio watch collection. The logo and overall look of the website should have been better, for their service quality as the logo and interface of the website look skeptical.
Overall a great buy from Casioindiashop.com
