These controllers work great. My old ones were so worn out they couldn't be used anymore and these ones completely bought them out. They work just as well and I haven't noticed any issues like lag or freezes. The only minor complaint is that they felt slightly different in my hands as they were unbranded. Only the plastic and the weight are slightly different. Unless you're a hardcore gamer this won't matter at all, but I wanted to add a small criticism. Otherwise a great way to keep your N64 running!
