Not impressed at all. You can't unplug the end while the valve is open because there isn't enough clearance. Even when you close the valve it's SO hard to unplug because it's tight.  The mechanism just doesn't work.  Had purchased ones by Melnor before at the store and they were much better but I can't find the ones with the on/off valve built in.  Also, Amazon the seller wouldn't allow a return on this product.  No clue why.
