I also remember buying 2 third party rubber lens hoods for my 18-55 kit lens (can't even say that without laughing now!). Pointless garbage. Also bought one of those lens caps that have a string attached so you don't lose it. It just flaps about annoyingly and gets in the way instead! Pointless!
I love the rubber hoods for shooting through windows, they eliminate most reflections if you have 'em flush on the pane, and allow you to shoot under an angle doing that. And those strings are brilliant - I attached a bunch of those to the zippers on my motorcycle jacket. That way, I can operate them with gloves on
And I have a bunch of stupid gizmo's - I always buy cheap first, if I use it enough and I can find the shortcomings of whatever it is, I buy something more expensive. Goes for most everything, tools, food, furniture, 400D>5DIII... The plus side is: I frequently find I don't even want to use stuff before spending serious money, and I have a lot of stuff that I do use which doesn't need to be expensive. Flash diffusers, the no-name LP-E6's that I use, rings, remotes, cords, gloves, you name it - I paid pennies and will never need more.
I bought a micro camera to clip onto Fluffy's collar to see what she did all day. The camera was set to take an image every 10 seconds. I managed to capture 9 hours of sleeping cat.
I tried it on her outside. She came back without camera and collar. I never found it.
This had me in stitches. Pet Fluffy on my behalf, will ya
