These are cheap, light weight plastic lights. Not at all as pictured. There is a big difference between these and the metal ones that I have seen used by professionals. The only plus to them being cheap was there were more of them.

Ex Output:
Bad review

If you are a fan of this band you really should pick up the Limited Edition cd version as it has 4 live dvd's and 1 music video so all 6 shows can be watched in their entirety. It is worth every penny, I would buy anything they put out! All these Dvds include interviews with members past and present so it's definitely money well spent.

Ex Output:
Good Review

I've used these kind of cases before and this one was not the best. The case slides open too easily - I have to tug it open. Other times my credit cards would slip out from under it. It's a cheap case, but you get what you pay for.
