Looking for everyone’s opinions on this new concrete pumping device. I have tried it and it works great for keeping splashing down and stopping concrete. It is spring loaded and opens if pump is accidentally turned on 

depends on cost, but operators are not going to want and lug that heavy piece of pipe around when an aircuff does the same job with ease. Also i'm assuming it goes on end of hose where hose guy is pouring to be able to close handle? If it goes to  plug up and the hose  whips that would act like a wrecking ball!! good luck let us know if you use it and post some pics

im sorry i know it goes on end of boom like a rams horn, but id be worried about that handle we tryied rams horns in the past for icf they were a pain in the ass.  3" flat hose is all we use now and they work perfect every time this is of course just my opinion 

No steel on the end hose. Who wants to go back in time 15 years.

No go.

An endhose ends with rubber.

Delivery hoses with attachement are a no go.

That's nothing "new" that thing has been available for over 10 years. Nobody wants to risk attaching it to their tip hose. It's dangerous.
