Techniblock SPF50+ Sun Spray 340ml

Received the wrong product (flat head instead of spray) and was told by the seller ‘that’s the same’ so I post review here.Product is difficult to apply and I question the protection it gives - using 50 every hour, I had no sun burn I still get red.The spray says to be water resistant but it doesn’t seem to be the case. Pretty painful if you get it in your eyes so wouldn’t advise it for children
