This cooler seems to have it all, I was particularly interested in the wheels and the ability to add in a bluetooth temperature sensor.
Although the build quality seems nice, unless a cooler does an excellent job retaining ice it is not a good cooler regardless of features or quality. And it's one of these extra neat features that causes the cooler to NOT be a very good cooler - the double drain plugs.
I'm sure it seemed like a good idea - hey, let's add a 2" drain so we can save a couple minutes when it's time to put the cooler away! And it could be a good thing, but the drains on this cooler are implemented very poorly - they have zero insulation. Zip. None. Nada. As in not even a little bit of token cheap foam so that it's obvious insulation was at least an afterthought.
What this means is that both drain plugs sweat profusely, and lose cool from your cooler at an alarming rate. 20 lbs of ice (a fairly typical load for a 50 liter cooler) was completely gone after about 3.5 days outside in the shade in 60 - 80 degree weather. This is $20 Coleman cooler-esque performance. Also, and just as important - anything that your cooler happens to be sitting on is going to get very wet. Hope you don't have wood floors.
Finally, don't count on Kysek for customer service. I emailed them asking if they were working on anything to improve their drain plugs. 2 Business Days later, still no response. Silence. Not even a thanks for your question automatic reply.
So, this cooler is going back. It doesn't matter how good an idea is if it's implemented as poorly as these drain plugs.
So on the 3rd business day after posting this review I received a response from Kysek. To their credit, they offered to send me new drain plugs or RMA the cooler. However, this is a design problem not a manufacturing defect so new plugs or a new cooler won't change anything.
After further research, sweating drain plugs is not a new problem among rotomolded coolers. However most coolers only have one small drain which which results in much less heat transfer. Apparently, this issue can be mitigated by purchasing a rubber or cork stopper and plugging the drain from the inside of the cooler to restore some insulation at the drain opening. Not the most elegant solution but definitely cheap and easy!
The problem with the Kysek cooler again is the 2nd, XXL 2" drain hole. Good luck finding anything to plug that! My suggestion to Kysek was to create a new drain plug with a couple inches of rotomolded insulation and rubber seal on the inside. This would pretty much restore the full integrity of the insulation at the large plug and could be made as a retrofit for existing coolers. Wouldn't be too difficult or expensive but would require actual product development and testing resources.
I'm not holding my breath, but this is what it would take to turn this into a great cooler.

this is a better product than yours2018年6月14日 - 已在美国亚马逊上发表
Sorry Yeti, this is a better product than yours. Very nice and easy to mover around. It did an excellent in full sun on top deck of fishing boat for two day fishing trip. The only draw back was I underestimated how large this cooler was. couldn't see in a store to judge size, as a result I got more cooler than I needed.
Great but HEAVY2018年4月24日 - 已在美国亚马逊上发表
This cooler does work as advertised. It keeps our drinks cool for a very long time. The only complaint I have is that it's nearly impossible to move when it's full of ice and drinks. The wheels are good if you're on pavement, but when I'm lugging this thing across the soccer field, I'm wishing for my $25 Coleman
Super strong, well designed2017年8月26日 - 已在美国亚马逊上发表
This is a beast of a cooler. Super strong, well designed, full of features. I have had lots of coolers and this one has the best closures of any of them. Easy to close and easy to open, yet has a very positive closure. The size is bigger than other 35 qt/ltr coolers - it is the extra thick insulation.
