The cord is irritatingly too long, and the extender expands too easily. If you need them at the longest length (like if you have a long head) than it shouldn't be a problem but it's annoying always needing to adjust. And when I bend down, they slip a little off my head.

The extenders gave me that "extra lift" I needed on the Stability Ball chair.  Could use another inch or two, but it too bad the chair itself isn't built taller to begin with.

works very well, extends easy. Great for the bigger cars of most wifes

I have had my extender for more than 10 years. It is the best travel accessory I own. I am over 6ft and it is an essential.

Unfortunately my glasses are thick on the ends, and the Keepons wouldn't stretch over them. I had to buy a more stretchier pair from another company in order to get what I needed.

This is supposed to be expanding.  They sent a spare pole which should be for expanding but the spare is not able to fit both of the other poles to fit into it.  The send a 3Rd pole that is a duplicate of the end poles with the screw end for the decoration end.  So it doesn't expand to be as long as they say.  You end up with a useless extra rod.  If you don't need the extra length it's fine but why pay for expanding if you don't need it?

I find this very useful, but the tool has limitations.  first, the sliding "locators" are too easily moved.  They need to more tightly fit so that once you place them, they stay put.  Having the built in level is brilliant, of course.  Silly me, I didn't stop to consider this tool really only works well when you are hanging items in a large wall space.  The very length of the level (3 ft) prevents you from being able to use it  on partial walls or recesses.  Lesson learned.  I still find it helpful in large wall spaces.  B&D - you need some improvements to make this a 5 star tool.  1.  Tighter fitting locators (as mentioned before). A smaller overall length with the ability to expand would be ideal because then it would be applicable in many more situations.

All the extensions were .002-.003" oversized.  This may be ok if you are using them just to extend the reach of an indicator.  However, if you need to use them like I did, to extend the reach on a depth indicator or an indicator in a fixed mount, your measurements will be off.

The extender definitely suited its intended purpose and helped support my arm, unfortunately I've broken two of them over the past 6 months. I won't be purchasing a third and will be looking for another similar, better constructed, product.

It was hard to get the rods to stay in the correct place.  But it is the only rod extender I've found that gives you the flexibility to change the height

GOOD FOR THE PRICE, BUT WILL STRETCH OUT EASILY

I was not impressed with these waistband extenders. The strips had too much fabric at the end which causes it to poke out.

The cables aren't long enough for the ceilings in my garage.  I had to rig up an extension to get it down low enough to easily load awkward/heavy items.  Other than that I just wish it weren't so expensive, I might buy a couple more if they were cheaper.

These work as advertised, but they are bulky on the receiving end so be aware of that in your application

Works as promised but I doc it one star because the hoses aren't long enough to give it the 10 feet it suggests.  It's very difficult to find extenders that fit the Intex hoses with the ring nuts so had to place it as far as the hoses will take it.

I bought these to hang 30lb light fixtures on a set of wire shelves for my seedling cart.  Between the wire hangers on the light reflector and the six inches this product adds to the distance it can be hung from the top of the plant cart, it takes away a lot of shelf space.  Also, the carabiners that you attach to the cart are not already attached to the rope.  It took me a little while how to figure out how to tie them on with a strong enough knot to support a 30lb reflector.  Let's hope the anchor bend from knots.com is sufficient, or I will have lost all of my seedlings.  Also, I have not worked with any other rope ratchets, so these concerns may be the case with all of them and not just specific to this product.  Otherwise, they appear to be well constructed and sturdy, and they are super easy to move up and down.

Perfect for what I wanted...an extension that's not too long and not too short, but just right
Works great too
