This is a fantastic mouse. This cannot use weights, but I don't use them usually so I don't see any downside. The battery lasts for a very long time while gaming. I imagine you'd have to play for more than 10 hours to kill it, I have not managed in a single gaming session even with other light computer activities throughout the day. The battery also recharges quickly. I am 6 foot tall and this mouse fits my hand comfortably, My 5'4 wife also thinks it is not bad with her tiny hands. Very satisfied.

This a Fiesta Island is huge! So far so good. We bought it to replace a large float that didn't last.....hoping to get more than 2 months out of this one. Seems very sturdy.

This alone is worth it's weight in gold just for "Wall Breaker". I burn 500 calories a day playing Wall Breaker. No need to play anything else. It's similar to a kick boxing game. Blows all the other games away.

Love this contraption, sure helps keep the skeeters away from my deck & this year I was amazed at how well it controlled those darn, nasty little gnats. Could not believe the number of those ugly little critters that ended up on the tac and also in the basket.
