Brita Sport Water Filter Bottle

At first the bottle was great the filtered water tasted great. I bought this because a co-worker of mine recommended it. Then about a week later it kept getting hard to squeeze. I'm a strong guy it shouldn't take me all my strength to get the water out but it did. So since I bought the double pack figured I would switch the filter. After switching the filter it worked normal again for about another week. So then after letting the previous filter dry out a week I put that back in and it worked once again.Now I am in the filter swapping game to get simple water. Not sure if all the filters are that bad. My co-worker doesn't have any problems with his filters but both of mine did. Also the bottle is very hard to clean. I had some mold built up from over the weekend on the bottom. I recommend getting a good brush to clean it. If you still want to buy it. I tried the dishwasher and it didn't get in there very well. Also after washing in the dishwasher my bottle finally started with the leaks that everyone is talking about.I was tired of walking around work with water all over my shirt and decided to get a new water bottle. The filter is what had me buy it in the first place but I would rather drink unfiltered water than wear my water every day.
