Spotted a nice little Cobalt Jive 561nm laser on the bay for very little money, so I bought it. It arrived yesterday, packed in a jiffy bag (actually, 3 jiffy bags, 1 inside another); I unpacked it and when I took it out of the packaging, I could hear the distinctive sound of loose parts inside.
Thankfully they've agreed to refund me.
This is the same seller who bady packed a number MG643 krypton lasers resulting in 4 ending up with broken tubes.
It's a real shame, as the 561nm DPSS lasers are quite a rarity, so I wanted to add one to the collection.
