Lamination Issue July 12, 2018
Reviewer: Robert from Norwood, ON Canada  
After about 5 brews the interior has a lamination issue  to the exterior I now have a large bubble on the inside.  I contacted OBK, I was told its plastic don't put boiling water in it.  I have never put boiling water in it.  However MASH TUNS do expect MASH.  my brews call for 75 to 80'C degree HOT WATER to strike.  I am not impressed.

It is a great performer, just not for a long time.

Great Tun May 4, 2018
Reviewer: Will from Victoria, BC  
As far as cooler mash tuns goes this one is really good. We have done 20+ batches in this thing and haven't had any issues yet. It holds heat well and the false bottom is great. No stuck sparges yet. It does take a little work to figure out your water to grist ratio since the false bottom keeps about a gallon of water away from the grain. If you use brewing software like Beer Tools Pro or Beersmith you can factor this in and it makes batch to batch consistency much easier. The area where the valve is placed on the bottom is a little thin but this is to be expected with a cooler. It doesn’t leak so no complaints. This thing is also huge. Large enough for any 5 gallon batch well into the 1.100 gravity range. Also works for 10 gallon batches if the gravity is reasonable. Over great entry level setup for a great price.

Great MLT January 31, 2018
Reviewer: Brian from Calgary  
This is as good as it gets for a picnic cooler style mash tun. Some of the concerns I have read are quite ridiculous, of course you will have to account for dead space in your HLT and MLT, you should build that into your brewing software calculations. Of course some particles will get through, this isn't a recirculating vessel, its a cooler with a big filter. I have brewed about 25 batches with mine and have zero complaints whatsoever. Is it a 500$ SS mash tun with a chugger pump ? No. Is it a high quality MLT with good fittings and a false bottom as good as any? Yes .

OK product but concerned January 15, 2018
Reviewer: RonV from Ottawa, ON Canada  
I've used the vessel 4 times since purchasing.   It works fine in terms of holding temperature, the false bottom adequately filters with little to no grain slipping through.  

However, a concern arose on my last brew when the vessel began making an odd creaking noise during the initial duration of the mash period.   later, after emptying the vessel, I noticed the interior wall had buckled with heat as if it had de-laminated from it's original form.   I'm also seeing pressure indentations on the bottom surface where the legs of the false bottom sit.

we'll see over the next number of brew days how well this thing holds up... I'll be mighty pissed if this thing pops a hole with such minimal usage.
