OSI QB300 Multi-Purpose Construction Adhesive, 28 oz, Cartridge

First and foremost, I want to stress that this review addresses Amazon's shipping practices with these and similar items, and NOT the products themselves! This is probably not the fairest way to address this issue, but it's a bad enough issue that I feel that this absolutely warranted, and I simply hope that people will read the comment and not simply rely on the single star rating to formulate their opinions with regard to these particular products.If you order any of the large (28 oz, 29 oz, 30 oz) tubes of construction adhesives, caulks, acoustic sealants, etc., from Amazon, the odds are very slim that you will get your package undamaged. Basically, if these items are packaged in such a way that they are allowed any 'slack' to slide in an end to end fashion (as opposed to a side to side 'rolling' movement), even a mere couple of inches or so, you will have a mess when you open your package - and it'll be smeared all over EVERYTHING in the package.These large containers are constructed of fiber tubes - which look like large biscuit / cinnamon roll / etc. cans from the refrigerated section of your local grocery store, the type that you strip off the outer slick foil / heavy paper layer before you hit the can on the edge of your countertop to cause it to pop open. These tubes contain the adhesive / caulk / etc. payload, which is held therein between a rear plunger and a thin metal endcap with a plastic nozzle attached to the fore end, and a foil-type seal is utilized between the base of the tube nozzle and front end cap to maintain the anaerobic condition of the payload substance carried therein. As most well know, these tubes are simple items to utilize. You simply cut the tip off of the nozzle, puncture the foil seal via the tube of the now-cut plastic nozzle, and then place the tube in a 'caulk gun' that will, in response to pressure created by pushing the rear plunger forward with successive compressions of your hand on a handle (or other similar source of pressure created pneumatically, via a screw plunger system, etc.), force the payload material out of the nozzle for application thereof.The problem here is that if these tubes are allowed to have an even quite minimal area within the package that will allow the tubes to slide 'longways' (end to end) during transit, you can almost be guaranteed that more than anything else, you will have a mess on your hands at receipt.The afore described thin metal endcap and foil seal is precisely that - thin - and not at all robust. So, when these tubes are allowed to slide forward, it takes VERY little such sliding to create enough inertia to cause the nozzle to be rammed through the thin endcap and foil seal when it's handled and shifted about during transit. Then, quite obviously, the payload escapes around the base of the nozzle and goes everywhere in the package, coating anything and everything therein. The punctured tubes are ruined due to the fact that they are exposed to air and they begin to harden quickly, ruining the damaged tube. The payload is almost always a material with 'glue-like' properties such as caulk, construction adhesive, etc., which then coats everything in the package, making any uncompromised tubes not only a mess and handling nightmare, it more often than not causes serious issues with placing these tubes into whatever device you will use to apply the material. Even when you are able to remove the hardened material from the outer areas of these 'undamaged' tubes, you will often have to tear off a considerable amount of the fiber tube to do so, and we all know what that sort of action does to a can of biscuits. Of course, anything else along for the ride in the box will be fine - if you don't care if it's coated end to end in a messy, sticky, and soon to be rock hard substance. Rolling side to side, even considerably, causes no such problems, but even slight end to end, 'longways' sliding is a tube killer.I want to stress that this is an issue that will NOT be addressed, and I say that after exhaustive attempts were made by me to do just that. I even went as far as creating a MS Paint image showing the extremely simple manner in which this can be easily addressed. After about five or six shipments, along with extensive contact between me and Amazon, I finally got them to start using a box that addresses this issue. The problem then, however, was that the box I refer to here is rectangular, and NOT square, so after two successful shipments, the third one came in with the tubes oriented 90 degrees to proper, and of course that once again allowed end to end sliding and a huge mess. When I had to contact them with this latest development, they simply started using real long and totally inappropriate boxes once again that ABSOLUTELY assured some degree of damage to the items. As ridiculous as this sounds, I'm not kidding, exaggerating, or lying here in the least, I can assure you of that.I want to stress that my interaction with these items shipped from Amazon involved numerous orders of considerably large quantities of several variants of large fiber tube products, and my discussions and explanations with each successive issue was extensive. As silly as it surely may seem, as I said, I even went so far as to create diagrams and/or send numerous pictures of this unbelievable fisaco, so I will never assume that this will ever be addressed, and I would aver as much to you as well.Good luck if you order these sorts of items from Amazon. You will most surely need it. I say that as an absolute fan of Amazon, but one who would never now even remotely consider ordering any such similar items from them EVER again at ANY TIME WHATSOEVER in the future, period.

We got it and one tube was blown out and unusable
