Query: This is item is junk

This item is poorly made. The directions are so poorly translated and spelled that they are laughable. The 2 thin/cheap strips of velcro intended to keep the collar closed pop open as soon as you get enough traction to feel it at all. The release valve does not work. I had to pull the bulb off the end of the hose to deflate the device to put it back in the box. I returned it the day after I received. The "expedited" shipping took almost a week.
