My family only buys Contigo bottles- I swear by them because I hate leaky bottles and impossible to clean parts, and for the most part, they really do last forever, so they're worth the higher price to me. This particular one is the only one we've ever had issues with. I bought this for my son (now 3 years old) and sadly, the design began to wear off immediately. Not a huge deal, but not a problem I've had with any other Contigo bottle we've bought. The bigger issues for me were, 1. My son dropped this bottle on the sidewalk once, and the plastic lid has never closed all the way since. It's a shame because the button-trigger lids are a big part of why I buy this brand- kids drop things, but the lids usually keep the dirt out. And 2. The silicone spout never seems to get fully clean. I clean them regularly and thoroughly (which is why the design is nearly all gone already!) but the spout always looks dingy and stained. We only use water bottles for water, so I'm certain it's not dye residue from other drinks. It still holds water and does not leak unless squeezed, so it's still usable, just disappointing quality compared to the rest of the products we've tried from the brand.
