Product: AMPRO  T70569 Coil Spring Compressor
Overall sentiment: negative
Customer reviews:
Wins award for biggest POS I've ever bought. Basically made of soft pig metal, it bends and flexes and warps with ease. There is no way to grip the coil and many times it slipped off under high tension. Worse, it's advertised as a motorcycle spring but it is NOT.  The tongs are far too long and hit the shock body.  These things are dangerous and slip off easily.  AVOID AT ALL COSTS. 
 These are smaller than my other set but the prongs won't fit between the coils on my motorcycle shocks. They aren't long enough to grab the ends even if I could get to the ends without damaging the shock itself. I would have returned them but I ground down one prong in hopes of getting it between the coils on the spring, but no luck. 
 Stay away from this...
I bought to replace the struts on a Sonata, and almost loose a leg....
The quality is ok, but they are not good enough for the job.
I was doing it very carefully, but the problem is, they slip and start bending and then let go, long story short, I ended up taking the coils to a shop to get compressed on a professional machine..
I'm an avid Do It Yourself, but the risk with this is just too high...

If you still want to try ti do it yourself, get the ones with a locking pin, that will give you a better chance... 
 Very soft metal for the bolts bend very easily 
 Cheaply built and downright dangerous ... Like to have broken my hand when they slipped off my compressed coil ... Rent or buy good ones! 
 Junk. Bent on first spring. Buy real ones. 
 these things are s***ty yo poor everything and cheap ass hell 
 The threaded shafts can't handle more then 200 lbs before they bend. The hooks slip off without warning
And they can't handle much more then the shafts.

I tried to use them on my Suzuki vitara sport. This car is 3500 lbs. 4 of them are not strong enough to compress one spring on this very light car. They broke off and injured me.

Do not buy these unless you enjoy broken bones. 
 I bought this spring compressor for a strut replacement on a 94 Honda civic.  The first spring I compressed, one end of the spring compressor came off.  Lucky for me, the second spring compressor held on the opposite end.  This tool is of poor design because each end has only one point of contact on the spring, and therefore the tool will twist as you tightened down the spring.  I stop using this tool, rented a tool from the auto parts store (OEM 25550 spring compressor), and safely completed by 4 strut replacements using a different spring compressor.  In my opinion, the tool is dangerous, and should not be sold on Amazon.com.
OEM 25550 is much better design, and much more safer to use. 
 Not for smaller / motorcycle springs - only for large car / truck springs. 
 cheap you get $12 tool
