[This review was collected as part of a promotion.] As a Panthers fan, the design immediately caught my attention, but I've been very impressed with the toothbrush as well. My teeth feel noticeably cleaner than they typically do with a manual toothbrush. I really like the idea of the pressure sensor giving me immediate feedback on when I need to ease up a bit. I also appreciate the built in timer keeping me on track as well. The Panthers branding is a great bonus and looks awesome on the black handle. Overall, I've enjoyed the iO2. It combines features that are actually useful and the team design makes it fun to use.

[This review was collected as part of a promotion.] Love how quiet this one is compared to my other oral b electric toothbrush. Love that it is panthers themed. I feel the vibration could be a little stronger. Like that it is lighter than my other one. Not sure of the battery yet.

[This review was collected as part of a promotion.] This is an awesome tooth brush! It has many cool features like my favorite football team on it. It also has 3 different settings you can use. If you've never used an electric tooth brush the first setting is for you, the sensitive setting or if you have sensitive teeth. The second setting is is gentle clean and the third setting is daily clean. Each setting has its different vibrations. No matter which you choose if you brush too hard it will vibrate less and flash red telling you to brush more gently. There's also a 2 minute timer built in it. This toothbrush is so fun to use. One charge will last up to 4 weeks.

[This review was collected as part of a promotion.] I am obsessed with this tooth brush it works so nice, and it's quiet. It has an easy to remove head and a really nice handle. The app I'd really easy to use, and it's easy to pack up on the go if your traveling.

[This review was collected as part of a promotion.] I really like this toothbrush. The handle feels comfortable and easy to hold, and it cleans my teeth really well without feeling too harsh on my gums. The pressure control is helpful, and I also like the simple 49ers design. Charging is easy and the brush head is simple to attach and replace.

Little bit hard to get use to though wouldn't go back to old electric toothbrush. Teeth feel cleaner and easy on the gums.

I think the toothbrush does a great job cleaning the teeth, but one charger did not work straight out of the box. To avoid the hassle of returning, I decided to just keep it and use one charger for both. Now the other charger has stopped working! So that is very frustrating, especially considering the price. The toothbrushes also collect a lot of build up and gunk in tiny little crevices even if you're careful and rinse and attempt to keep them clean. To top that off, I just bought a pack of replacement heads which are not cheap. Money wasted. I expected better quality.

Replacing an older model. This is definitely an upgrade!

Liked the previous better.
