### ⭐⭐⭐ 







  
  
    I'm sure it would have been great.... but!
  

*by S***E on Reviewed in the United States 🇺🇸 on December 19, 2022*

Basically.... the attachment length is too short for tapered cylinder heads.  My old Sears tester has a longer thread attachment.  I purchased this one to replace my old one and the needle on my old one was accidentally injured in using it!  However, I had to go back to the my older tester.  Has anyone else had a problem with the length?

### ⭐⭐⭐⭐⭐ 







  
  
    Good tester for incidental usage
  

*by T***N on Reviewed in the United States 🇺🇸 on October 12, 2011*

If you're not a pro but want to know if you have even enough compression among cylinders, this is your tool. Used it to check my outboard compression and the tool works as advertised.For incidental usage I would recommend this tester.

### ⭐⭐⭐⭐ 







  
  
    Decent budget compressor
  

*by Y***M on Reviewed in the United States 🇺🇸 on April 4, 2013*

Good budget compressor, I have used this on small engines and chainsaw motors mostly.  Ended up getting the adapter set because this only comes with the stock size for plugs.  If you need it for more than just automotive you may want to get the set that includes all the adapters.  For a value-priced tester it really does a great job
