Dev products question?

So I want to use dev products for people to purchase a static item, a chaingun that they buy permanently. I understand the norm is to use datastores to save information about the player, but my friend tells me it's risky to do so, because if the data corrupts then people are losing their robux (essentially). Is http service the only alternative or are data stores safe enough for me to do this?

DataStores should be safe to use, since ROBLOX is advancing to them and they are no longer in a beta stage. Data Persistence however may become risky after their little save instances error a few weeks ago. DataStores are becoming more reliable, and I have only once encountered an error with them that was contained in one server and has never risen again.
