I haven’t bought from temu, but I’ve bought loads of stuff for various things on similar sites like aliexpress. If I have the time to wait for the shipping, it’s the exact same components as I buy in electronics supply stores here, but at a fraction of the price. I prefer to not pay a 300-400% markup for no real reason.
I recently had massive issues reaching my home network from hotel WiFi. I couldn’t even connect my regular VPN on their WiFi, I tried a bunch of stuff with different ports, TCP/UDP, different protocols, nothing seemed to work even for my proton VPN.
I managed to get mullvad running though, then I could connect with tailscale (with mullvad VPN still running) and then disable mullvad after tailscale connected. Tailscale then didn’t drop the connection.
Weird work around, but it was consistent.
