Honestly, i wondered why i didn't buy an official wave-bird controller from nintendo, when i was searching for GC controllers, and while i was looking, i found out that it didn't have the motors in them, they said it was to give a longer battery life, and i can see that, everyone likes it, but its a matter of preference.
So, I preferred feeling the vibrations of my games, it makes me feel more immerse, and bought it with this in mind. sure, you'll only get 3-4 hours of gaming with this pelican pad, but honestly its the best 3-4 hours you'll get
(I recommend that you keep a lot of rechargeable batteries if you get this)
and if you don't want to be bothered with that, just get an extension cable for your wired controller
