Anyone tried these before?

There's tons of them to buy and for about 4/5$ where i live. Are they considered good quality for a domed pellet? I just want a cheap alternative since a jsb tin is about 15$ and I found domed pellets work better than my pointed ones. Would you guys recommend me giving them a shot? And would there be a possibility they'd work better than the jsb?
