Review on Efficient Brake Bleeding Made Easy with Phoenix Systems 2104-BOT V-5 Reverse Brake Bleeder by Patrick Reid

I had this re-bled after having to replace the brake caliper and all the brake lines and hoses on my truck, hooked it up and when it was poured all looked promising and it stirred. good in the bottle. Plugged in and it just pumps fluid around the bleed threads, nothing seems to get into the system. Try to slowly close the bleed valve by squeezing it and when it stops pressing against the bleed valve it just stops squeezing all the way. Then I tried comparing it to a regular small handheld vacuum vent from a port freighter, the port freighter draws liquid, this thing only draws air around the vent threads, no liquid. It doesn't seem worth the time and effort I put into continuing the normal process of bleeding two people.
