Which is the best double sword anti theft door lock cylinder

It's all about the same, the Meilibao propaganda is good, but the quality is not good, there are too many bad, it is difficult to insert the key in about two or three months or difficult to pull out, this is why the manufacturer sends graphite powder, if you don't send it, it is more bad, this is the common problem of the Meilibo lock cylinder, if you want to buy a good lock cylinder with high security, you can consider the Jiabo super C-level lock cylinder, the quality is good, but the price is a bit expensive, but I think it is worth it, because the most important thing about an anti-theft door is the lock cylinder.

It's all blade anti-theft lock cylinders, but Meribo's key is a little more refined, the lock cylinder of the double sword feels a little card-like, and the key is also a little rough, anyway, it feels a little better than Meribo's.
