Bests & Worsts Reviews from Amazon

I have had my 30 oz Rambler for about three months now and love it! There is just one problem (and quite frankly, it's a rather big problem). The magslider lid that comes with the Rambler is one of the worse lids I've ever used. It leaks! Alot! I live in Wisconsin and I drive a truck for a living so rough roads are a normal part of my drive. Every bump, every tip, and any movement by the truck or Rambler the lid will leak around the closed black slider. And forget about laying the Rambler on your seat or tipping it at all. You'll have to spend time cleaning up after it. It is quite frustrating that a great product (and a rather expensive one) cannot make a lid that does not leak. Because of this, I can't say I'd recommend the Rambler to a friend, so long as it comes with the Magslider lid.
