Product review (3 stars): Cramped space?  Can't install.
While it is a good idea to change out your hoses every few years and these have an innovative concept, they also have a serious probloem:

The hoses are bulky, thick and very inflexible.

I have a very cramped laundry space and getting these hoses in was an exercise in madness that I gave up on.  They are almost twice as thick as standard hoses and very stiff.  Getting them to bend where I wanted to resulted in the hoses turning into gigantic springs that would uncoil and thrash about like a wounded snake.

The "leak alert" part is about four times as thick as a regular hose and right up against the coupling used to attach to the water outlet.  If yours are recessed into the wall as mine are this becomes almost impossible as there just isn't room and there's a rigid five inch or so length that will not/cannot flex even a bit so if the angle of the valve on the wall is not just right, you aren't going to hook these puppies up without adding a short length of adapter hose.

Instead of these, I'd suggest good quality hoses with a braided steel outer jacket.  I've used such for a decade and a half without issues and Amazon has them:
