Great for carrying my ResMed AirMini CPAP!

I was thrilled to find this bag to carry my ResMed AirMini CPAP machine. ResMed offers two different cases for the AirMini. One is the $29.99 ResMed AirMini CPAP Machine Travel Bag that just holds the AirMini CPAP device. The other is the $61.00 ResMed AirMini Travel Bag which holds all of the needed AirMini items, the CPAP, the hose, the mask, the power brick, etc.First off although I’m sure both of those cases are of good quality I felt that they were way overpriced for protective carrying cases. Plus the $61.00 carry all travel bag does not have a strap to hold the bag onto my rolling luggage handle. Perhaps it does, but I could not see it in any of the photos.This lunch bag has two separate handles. The one that goes across the lid is the one I use as a strap for my luggage handle. Fits perfectly as you can see in the photo of this review. I store the shoulder strap in the cover pocket. Everything stores inside this expandable lunch sack without needing to be expanded. Nice to have the option to enlarge it though! You can see that I use a Mavic Pro drone controller case to hold the AirMini CPAP. It’s like it was made for it!BTW the power strip in this photo is one I carry to use with my CPAP in the event the wall plug is further away than the AirMini’s power cord will reach. It also has four USB power connections which I find really convenient.Everything fits nicely and there’s even a separate sleeve for the hose. BTW I use the P10 mask so if you use the larger ones just expand the lunchbox to accommodate it! Done!

A Versatile and Durable Choice for Busy Days

This is the best lunchbox I have purchased in over 10 years. My 11-year-old son has been using it daily, as his days start at school around 8 a.m. and continue with tutoring and sports until around 6 p.m. This lunchbox has truly stood the test of time and daily use.I bought this lunchbox for its versatility, and it has exceeded my expectations in every way. One of the things I love most about it is the fact that it has multiple compartments, allowing me to pack different snacks for him to enjoy throughout the day.What my son loves most is that, in addition to being able to carry it in different ways, his favorite is attaching it to his backpack, leaving his hands free for other activities. The lunchbox's design and functionality have made it an essential part of his daily routine.Even on days when he doesn't need to bring a backpack, the lunchbox's advantage is that, due to its multiple compartments, he can conveniently store his snacks, a pencil case, and even his cell phone all in one place.The durability of this lunchbox has truly impressed me. It has endured daily use, and I have already washed it in preparation for the upcoming school year. With its vibrant colors and stylish design, it appeals to children, teenagers, and even adults.Overall, this lunchbox has been a game-changer for us. Its practicality, versatility, and durability make it a top choice for anyone needing a reliable lunchbox solution, especially for long days filled with various activities.

Perfect size when expanded

I don't know why so many of the luncxboxes are so small, however this lunchbox, when expanded, is the perfect size. Keep in mind that when it's condensed the insides take up a little bit more space. You lose some volume. Otherwise the lunch box is really nice! Also I really like the extra strap. I use this and so does my 4yr old!

Excellent daily lunch box!

Just the right size for our glass bento box style salad containers plus sandwich container, dressings, snacks, & freezer pack. Sturdy and keeps everything cold the entire day. Easy to carry - we use the handles not the shoulder strap. Love that there are two choices for using the handles. Read numerous reviews and glad I chose this. It is expandable so you can make it less tall when there’s less to carry. Even when full it isn’t huge. Great purchase - highly recommend!
