I gave it a 4 star only because it isn?t exactly waterproof. Perfect for under the sink on back of door . (Note for setup: It?s easy to put together and only took about half an hour for me to do alone). 5mm Gilded11. I dont know if this was just a lemon pair of shoes or if this is a design fault, but buyer beware. My solution is to empty the contents of the problematic ones into a bowl and switch them with the ingredients you dont often use or with ingredients that are thicker and less likely to spill. My daughter seems to be comfy, but then what does she knows about safety aspects? If DO LITTLE would design some handles designed for small hands to install on the steering bar, it would make me maybe a little more comfy, knowing she has a good grip at least, because with this set up (and my bike steering bar, which is kinda thick) she is more balancing than really holding on. I love how the QC35 (bluetooth) over the ear headphones work but I hate how they leave you with "headphone hair". Lets hope they make a 7 hour plane journey easier 0 buds paired quickly, easily & seamlessly.
