Overall sentiment: negative
Customer reviews:
hoses leak at crimp fittings complete junk 
 It had a strange dial faces which were hard to read. I returned it 
 It is advertised as a device that can be used for auto a/c systems.  But it won't fit the R-134 connectors without purchasing separate adapters.  I purchased what I THOUGHT they were saying I needed, but it wasn't.  What you need to buy is the 'quick-connect' connector, one for the high side and one for the low side.  I eventually ordered them, and am now waiting two weeks for expected delivery.  My local NAPA store will sell me the same thing--today--but for $37 for each one! 
 What the heck did i just buy?

I received a Manifold that had no handles and was missing a hose all together!

Not to mention that the color changing desiccant is not installed in the sight glass and to top it off it is not in PSI.

Just a really bad manifold all together. 
 Received item very quickly.  Went to use it, and found that the charging port on the manifold had damaged threads.  The protective caps were loose in the box, so I can only assume that someone else had already purchased and returned the item.  Amazon accepted the return no problem, and I will be ordering a replacement set as soon as I receive the credit for the return.

Aside from the damage to the unit I received, overall quality was pretty good for the price.  Hopefully the replacement will arrive with no damage.

UPDATE:  The replacement arrived today.  There is a crack in the manifold that runs from the high side gauge to the low side port.  The machining on the threads that connect to the hoses is horrible.  I will be returning this one, and shopping around for a better quality manifold. 
 Received fast but one of the hoses leaked I would of returned it but I needed  to finish the job I was on. I ended up using a hose off my old gauges 
 this is a cheap made set, not for commercial use, will mot hold up to everyday use,. I guess the saying is true, you get what you pay for. I can not recommend it. 
 You get what you pay for 
 You get what you pay for.  Not much quality. 
 Broke from the hose's.
