Brooms-
I believe brooms were invented for many reasons, and here are some of them.
Brooms help wizards get around without having to pass an apparation test. To take an apparation test, you have to be 17, but to have a broom, you have to have cool parents. When you have a broom, you can play qudditch, which is the most common wizard sport.
I think brooms are definitely a GOOD thing. They help wizards with many things. I can't think of anything except that they can be very pricey, that is bad about them. I personally think brooms are one of the best inventions in wizard history.

Very nice Dora!

Remembrall-

A remembrall is useful. It lights up, in the color of your choice, to tell you that you have forgotten something. I think it was created because too many witches and wizards were forgetting things. So the remembrall was created to help in the assentence to remember. Someone would use it if they were very forgetful. The only con to the remembrall is that it cant tell you what you forgot, so if you cant remember what you forgot then you would know you forgot something, but would't know what it was. This is definatly considered good magic!

A shallow stone basin with odd runes and symbols carved around the edge. When in use, a silvery light shines from its contents, which are bright, whitish silver, and cloud-like, moving ceaselessly. Harry thought the stuff in the basin looked like "light made liquid - or like wind made solid.It allows the user to recollect the past and scan through even the most minute detail, if needed.I thought the wizard who invented this was an old guy and he couldnt remember things, and he wanted to read through his memories again and again
