I had something old, but I replaced it.
Did your old one stop working?
Not really, but I feel like this one is better!
It is always good to get new things, they work better and look nicer. As long as you can afford it, it's okay to replace the old things with newer models.
Yes, but they both have the same purpose.
Replacing old things in your house can have several benefits, including making them more efficient. Just try to recycle what you dispose of or perhaps donate them to a group or charity.
