JSAUX USB to USB Adapters

I saw this exact JCAUX product first on Amazon US for $12.99 with a 10% discount few days ago. This product has the "Overall Pick" tag on Amazon US at the time of writing this review. This listing also includes 4 pcs (2 x USB A and 2 x USB C) like the photo shows.When I searched for data blockers on Amazon India, sellers here are selling for Rs 2500 and above which seemed very expensive for such a thing and most of these listings contain only 2 pcs.I again searched on Amazon India two days ago and saw this JCAUX product listed for Rs 999 and while the photo in this listing shows 4 pcs, the title and description only mentioned 2 pcs will be provided. I still purchased it considering it was the cheapest at Rs 999.To my surprise, I received all 4 pcs, i.e. 2 x USB A and 2 x USB C. I've tested all of them and they work perfectly blocking all data. Plugged in a USB external SSD to my computer using these data blockers and my computer couldn't even see the SSD show up under Disk Management.It's perfect for the price and the quality is great. It looks great too. A perfect accessory to carry with you when you travel and charge your mobile devices in public areas like airports, restaurants, hotels, etc.One suggestion to the seller here - please correct the title of this listing by stating it's 4 pcs, not 2 pcs.
