It took several weeks to arrive after my order, but the wait was worth it. I had two stubborn grease zerks on my cat tractor that refused to take grease for a long time. I set this new unclogger up and tried it out. SUCCESS !! It worked as advertised.
Very nice
Excellent description and delivery. Definitely recommend
..
Great product lousy shipping took 30 days to deliver
works good
The adapter going into the grease Zerk broke twice.The metal threads are thin piece of junk
leaks everywhere
It kind of worked, but the plunger blew up after five times using it on one grease nipple that was seized
This devise doesn’t fit in the sert. It needs a larger nozzle. Also the plunger is next to impossible to get out after it’s had grease in it. I don’t recommend this product
made great. just as described. spare seals and all.
Tools was as advertised. Customer service at first was rough at first. Lack of communication over shipping.
Awesome product,just realised I needed bsp so had to make an adaptor then worked perfect,first attempt!
