Can't comment on how durable it is and how resistant it is to a heavy drop or sharp objects because I just received it and put it on my watch. But it was easy to put on (literally and figuratively), it's almost invisible on the watch, and I don't see any negative impact on the touchscreen's functionality. I'd say even if it doesn't last long (or maybe a while, who knows) it's still a good buy considering the price, especially considering there are a few included in the package. Plus quickly shipped and delivered.
