The TKWide Straw Cap is praised for its perfect fit and high-quality materials, making it ideal for smoothies and cold drinks. However, opinions vary on its design and the functionality of the silicone extender. The cap is compatible with TKWide bottles and is dishwasher safe, but it is not leak-proof.

"Cap and straw with great. Very convenient and easy to clean."
"I recently was trying to find pack of stainless steel straws on Amazon and they were either too long or too short and was like why am I doing this? Klean Kanteen has great straws of higher quality for less money that can fit various heights. This 10 mm size is wide and perfect for smoothies. I actually wish they sold a silicone extender with the straw packs, and for 8mm size, but the 10mm straw included in this package can be the perfect height for 12, 20, or the 32 oz. TK wide cups, or any other cup you want to use it with. the straw itself is a little short unless using with 12 oz, but even if good length for your cup I recommend cutting a very short part of extender and adding it so steel does not scrap or bang against bottom of cup, making straw silent. It so functional and smart! I would love to be able add just extenders without buying another lid for my other Klean Kanteen straws. I posted a picture of two of 10 mm straws with extenders cut to different lengths and one of the narrow 8mm straws from a straw pack. Extenders only fit the 10 mm straws. The straw lid is great for casual use, obviously get a different style cap for travel or waterproofing. The default tk wide cap with folding straw lid also genius design!"
"Enjoy a smoothie all day without compromising the more intricate straw lid on you water bottle twist top. TK WIDE line for the win!"
"I like to splurge on soda water and this is the perfect lid for the tk cup. Only request is for a longer straw for the taller tk cups."
"Good design lid doesnt spill"
"I love this cap, especially because it is exchangeable with the other TK wide caps. It is not leak proof, but it’s not meant to be."
"I like the simplicity of this cap compared to other tkwide caps."
"I love this straw lid so much. Fewer parts and much easier to take apart and assemble for cleaning. Exactly what I wanted for my Klean Kanteens. Only downside is bigger single ice cubes can’t be used with this straw lid."
"Fantastic"
"I love this lid. I can put my bottle in a tote bag and as long as its upright its fine. It also doesn’t leak in a backpack side pocket."
