@MrShake : Ok, I'll try to explain as clearly as I can.
The thing is, you bashed the knockoffs, saying you should buy from a trusted source, that you have a good source, you will re-sell them and your source is ali.
I don't have a problem with you selling SSR's at markup. I'm sure that will be good option for a lot of ppl. Be open about it though, ali is a big place, you'd need to link to a specific item or at least a specific store.
Secondly, there is no guarantee that the SSR's you sell are not knockoffs either. They might just be from another batch with another triac or another factory. They might be genuine, but as your source is ali, you really shouldn't bash on the knockoffs to try to sell your SSR's, especially if you have no proof that yours are genuine.
Edit: Yeah, I checked brewtroller.com. So you got the 40A version. Off ali. Re-selling for $12. I wouldn't be so fast to call them genuine just because they've not failed.
So, you felt I attacked you. Well, maybe I did. But I hope you can follow my reasoning above. It just ticks me off, when you say you have a good source, just just won't share it with anyone, because you figure you can sell them yourself.
Also, I have *zero* interest in where anybody gets their SSR's from. I just thought the video I posted in the first post was interesting. All I ever claimed here was that, even though not up to spec, what you *actually* get for 5 bucks is not that bad. People seem to really take offence that it is not as advertised. Well, the same thing goes for buying "Ray-Bans" for 5 bucks. It may still be a good enough deal though. If you want something that is up to spec, can be trusted and has support, then you should buy genuine from a reputable retailer with a trusted chain of supply. It is that simple.
If you have five bucks and are willing to wait 3 weeks, the knockoffs seem to be good enough to play around with if you just don't put to much load on them.
