Query: Too Leaky!

I purchased the Avent bottles because I heard they were the best. They were very expensive but I bought them anyway. I am very disappointed with these bottles. They leak alot!! Not just a tiny drip here and there but streams of formula running down the bottle onto my son and his clothes. He is often soaked after feedings and I have to completely change his outfit. I tried not tightening the bottles so much and I must admit that it helped. But I still get about 1 leaking bottle a day. Just enough to soil me or my son's clothes. The only good thing is that they are super easy to clean. I am to cheap to go out and buy a bunch of bottles that are a different brand. Who knows if those will work either. But I would not recommend that anyone buy these bottles. More expensive does not mean better!
