QWORK DSLR Camera Repair Tool Kit - 3/8" to 3-15/16" Lens Repair Set, Anti-Magnetic 3 Tips, 6 Screws & 2 Hexagon Wrenches for Canon, Nikon, Sony, Olympus Cameras

I needed this to work on various telescope adapters that have index marks on each side of a ring and it works fantastic for that purpose. It's adjustable width lets me adapt the tool to whatever diameter I need. The adapters often get stuck from compression and this tool easily removes them.

I wasn't expecting a lot from this QWork tool for the small price, but it is superb. Don't let the price fool you. It is solid, heavy duty stainless steel, and very well machined and designed. The exchangeable multi tips also make it very versatile for use on any type of lens retaining ring. Even the tips are precision-made, hardened steel.I used this to rescue two Pentax lenses that had internal fungus, and was amazed that it was so solid and sturdy that I was able to unlock the factory-cemented retaining rings without using any solvent to dissolve the locking glue.This little $15 tool saved two $600 lenses. A best buy.

This is a very well made adjustable spanner wrench and worked perfectly to remove the lens ring on my spotting scope. It comes with extra tips to fit many applications.

I needed a lens wrench to open up the 4" objective on an old telescope for cleaning. This wrench worked fine - adjustable, well-made and quite affordable. I agree with other reviewers that the thumb screws holding the parts together do tend to loosen up easily. A bit of rubber cement in the threads fixed that. If you need to clean an optical assembly, this is a good choice for taking it apart.

I purchase several things on Amazon and was giving pretty in-depth reviews. From this point on, here's the new agenda…. if it works as advertised, is well made, meets or exceeds the description, is a value, and arrives in a fair amount of time, it will get a "star rating" equal to what my expectations were/are. If it doesn't meet these criteria, then I will most definitely and descriptively tell the short comings of the products and you as a consumer will not have to go through the trouble of buying the product without some background knowledge. If the sell pulls that item and relists under another description, I will put the exact same review on the seller's feedback page. Sellers have done this a couple of times in the past, and I was true to my word then as well as now. DR

The knurled knobs can’t be tightened enough by hand to hold anything in place firmly. This tool is okay but the setup is strange and the tool has scratched everything I have attempted to use it on.

Nice set for working on my cameras. Good quality.

It looks like it would twist and even fall apart while using it but I've had no problems at all. I wouldn't use it on heavy duty parts that require high torque to disassemble but it seems to be of reasonable quality.
