Spanner wrench
This spanner wrench is of decent quality and stregth for the task I had. I used it to remove the end cap of a 2.5" hydraulic cylinder in order the install new seals and o-rings. The end cap was tight and I had to hit the wrench with a dead blow hammer a few times to remove it. The wrench withstood the blows without damage.

Broke on 1st use
Seem like an ok made tool. Is a small wrench compared to the description handle is only 5" long not big enough to break free the gland nuts on my kubota loader cylinder itself so I used a cheater bar and the pin broke off. I know its pretty much my fault but I feel like the tool should be bigger if it supposedly handles up to 3" diameter nuts the 4 1/2 wrench might be better but I feel it's going to be smaller than I would expect also

Coil-over Adjustment Just Fine
I never thought this was going to accomplish what I needed, but was pleasantly surprised. I have Peak 2.0 Coilover shocks on my Chevy Colorado. There is an adjustment collar to adjust the lift. I bought these on a whim after looking at many others on Amazon, because the spanner wrench was mistakenly left out of my kit when I received it. I was skeptical as to whether this would fit, for one, and whether I'd be able to adjust my shocks while on the truck, or if I'd have to pull them off and get a spring compressor. To my surprised, I was able to use this to adjust the collar on both shocks while on the truck. I did add a lot of WD40 to the threads on the shocks, and they are very new, but I was still surprised to be able to turn that collar. Very happy with the outcome.

GARBAGE! Barely put any pressure and the thing snapped off first try!
Can’t believe how crappy this thing is! First try and I snapped the peg off! I could of bought a 10$ one and used it more than I did this one. JUNKKKKKKKKKKKK

Pricy but we'll built!
Had to modify for assembling and disassembly of motorcycle forks! I thought it was a little pricey but as they say, you get what you pay for! Sturdy and worked great for what I needed !

Works fine. Kind of expensive for what it is but I was having trouble finding a less-expensive alternative.
