do not buy if using larger spools!

it came without a "clamping bracket", which was not needed anyway.  the "spool support shaft" had 2 useless rubber bushings on the mounting rod, and I had to remove them before mounting in the pedestal.  then I found that the support shaft rod was too short to enable me to use a 3000' spool of line (4" height) without it being way off center.  either the rod has to be extended about 2" or don't use spools taller than 2". i can still use the support shaft by clamping the spool on tight with the cones, then clamping the bent end of the rod to a table.  it's a hassle.  i'm not going to return this ($16) - too bulky and more hassle, and part of it is still useable.  the base itself is well-made of heavy plastic, and I don't think I would have had any problem if I were not using a large spool.  nowhere in the listing did I see a limitation on the size of the spool.

This item does not fit trimmers with LH threaded spools.  This is stated in the installation instructions but not in the sales information.  Very disappointing!

I was unhappy with the connectors on this product.  The threaded portion of the connector was too short to properly connect to a standard female.  I was surprised about this as the 50 ft version that I had purchased a few weeks earlier had connectors that worked just fine.  Given my time crunch, I could not return the product, so I cut off the defective connectors and soldered on my own. A big time and money waste for me.  I would not buy the 25 ft version again.

Bought a 300 yard spool of 4lbs test. I did not receive a solid strand that was 300 yards. About half way through the spool I came across a poorly tied knot where two strands had been tied together. I almost missed it while spoiling my reel but I noticed one of the knot tags sticking out of my reels spool. I haven't used the line yet so I cant say anything about performance. Disappointed.

I was not satisfied to using your cotton thread.
It's so hard to run through each needle work.  Just like they are wet.
So I use it through wax paper to smooth up.  I'll never buy it again.
I'm not happy using it and I regret bought 4 of them.

Dont waste your time or money!!
Where to start?
Not enough tension for the line to spool tightly.
Not long enough for big reels.
When spoiling, the line hits the plastic spool after every rotation.
Also the line isn't doesnt spool evenly, you might get a more line the top, middle or bottom of the reel.
Made from plastic.
My device broke after one use.
I posted pictures of the problems I found with this device.

Dont used the small wire connectors that come in the package. They don't last. Go old school on wire splicing.

While this line is normally great, the spool that I received had so much memory that it was useless. It must have sat on a shelf, probably without proper climate control before I received it. It kinks and knots repeatedly on my surf rig. I am halfway through a beach trip and I have considered scrapping the whole spool several times now. I want to spend my time fishing, not untangling a mess.

See utube videos about disabling the auto feed.  This seems to be a common complaint that too much line is wasted. .80 round line is recommended.  I am curious to try winding up a bunch of empty spools with line sold separately to see if that is convenient/cost effective or not.

Junk!! The spool isn't wound tight and it tangles.  Ive tried to print with it 4 times and 2 prints messed up due to tangling and both times I had to tear my hot end apart to unplug it. I want my money back. 16 wasted prints switch to a different brand and no issues.

I have an older machine and these spools swing about on the spindle and then the thread snaps.  I will have to transfer them to standard spools to use them.

Attempted to use on NVX 1/0 gauge for my power wire from alternator to battery. Insulation on ferrule is too small to fit over the jacket of the wire. Metal part itself fits over strands snugly but the point of the insulation that I needed is to fit over the jacket a bit so no wire strands get exposed with any slight bends. Better off using un-insulated ferrules with heat shrink tubing.

this is better than the bump feed spools as long as you use the proper line as listed in the other reviews

Seems to be good cable, but would not recommend using the spooling feature of the box as it resulted in several kinks and wires with degraded performance.

I ordered this for my lx500 and the description said it was compatible.  Of course I didn't check until my current labels ran out.  The spool is too big and it won't fit in my printer.  My return window has closed so I'm very disappointed.

worst wound spool I have ever encountered. snags about every 10 minutes unless closely monitored to prevent snagging. I have cursed this spool countless times. Hopefully I got a bad one of the bunch but based on the price and my experience... I cannot recommend.
Used with a Wanhao i3 and Kossel mini

My particular application requires a spacer to offset the spool from the swingarm. The spools did not come with the spacer. The seller said they would get me sorted out but it seems they lost interest.
