Query: High Hopes

I had high hopes for this travel brush. I'm always looking for a convenient way to carry everything I need to attend to my Invisalign treatment and I believed that this could be the product to fill that need. Unfortunately, I was wrong. First of all, this product is advertised as coming with a replacement brush head and well as toothpaste. It did not ship with either of these items. My biggest problem with the OHSO toothbrush is the advertised "water tight cap" which can be used as a water cup to use while rinsing. This is not the case. The cap has 3 vents on each side as well as holes where the pocket clip is attached. This is NOT a water tight cap and cannot be used as a cup for rinsing.The search for a great travel toothbrush continues...
