While I like the build quality of this cooler, the main reason I purchased it was for performance (as indicated by most of the reviews and endorsements from family members). I have been using this cooler 5 days a week for over a month and i am very disappointed with it. At the end of the day, my blue ice blocks are almost thawed. My previous daily cooler was an Igloo Maxcold 24 can. The same blue ice blocks would be totally frozen at the end of the day and clearly would last through another day. Wish Igloo still made it!
I have noticed that the walls and bottom of the Engel have noticable "give" when pressed while the Igloo walls do not. I wonder if this Engel is lacking insulation...I will be contacting Engel's warranty department and see what they have to say...

This is an honest review for people like me who want to use this as a cooler. I will try to be as factual as possible. I bought it for a 3 day canoe trip. I didn't expect this cooler to hold ice for 3 days, but I wanted the water tight seal. I have no doubt this cooler/drybox works fantastic as a dry box or lunch box. But as a cooler it's very OK. I placed four 9"x10" freezer packs inside of it. Basically it filled the cooler. After an hour or so, I touched the cooler on the outside and felt that it was very cold. I picked it up and the floor it was sitting on was cold as well. Not good because the cold was getting through the insulation. I left it overnight in my dining room (4pm - 10am). When I woke up I checked the cooler and the freezer packs were liquid. This was in winter so my house was 68-70 degrees (Florida). The quality is still good and overall I really like it, but to call it a cooler is a bit of a stretch.

I lined the dry box with 1" styrofoam and repeated my experiment... the freezer packs are still half frozen after 29hrs.

Despite it's lack of insulation, I feel its a good, quality product.

Really cool lunchbox and also very spacious. I have put various stickers on mine and also changed out the strap and have receiver several compliments on how awesome it looks. I have also had friends purchase this lunch box because they liked how mine looked. It keeps all my stuff nice and dry in it.

2 months in and no complaints. Seems well made. I keep it in the rear bin of my truck with bottled water and ice. In August we were still averaging 100 degree weather. The ice was melted by about 3 pm but the waters were still plenty cold. Compared to my old ice chest (not sure of brand) the ice would be melted by 11 am in the summer. I have no idea how it would stack up to a yeti but I am completely satisfied with this one.

the 19 quart cooler was a great size for 2 people for a day. We took this on a kayaking day trip. Inside i fit 4 of the small square tupperware containers, each holding a sandwich, as well as 2 soda cans, 7 bottled waters or teas, and several capri sun pouches. (I took the tray out so everything could fit)
Granted, that didn't leave a ton of room for ice, but everything stayed nice a cold.

Insulation: ice doesnt seem to keep long in this cooler. I've used it twice, and both times the ice melted fast. Once the ice melts though, the water stays cold. Just make sure everything is in something water tight and you're good.

Watertight/drybox: 10 out of 10. The latched stay locked, even when flipped upside down in a kayak. No extra water got in, no water got out. I've only used it as a cooler, not as a dry box, but I have every confidence that it would keep everything well protected.

Handle: gotta watch the little handle on the lid, it'll pinch your fingers if you let it close on you. The shoulder strap does help with this.

Carrying: When it's full, it weighs a decent bit. Makes it a bit heavy if you have to carry it very far. It isn't too bulky though so that helps to compensate for the weight.
