The automatic feed spool on GrassHog advances the string without needing to bump on the ground. The benefit of this system is that cutting is easier as it constantly replaces worn out string, the down side that the usage of the string is faster than when done manually.
I have tried wounding the string by hand and found it a bit cumbersome and a bit time consuming, so I figured less than $5 per spool is not to bad to save me 5 minutes of time wounding and dealing with jammed string. Each spool contains 30 feet of 0.065 inch diameter round line. It is factory spooled and is wound tighter than when I wound the spool by hand.
To replace the spool:
1. Remove battery
2. Squeeze the tabs on the spool cap to release it
3. Pull the empty spool out by pulling directly away from the housing
4. Clean out the housing from debris
5. Make sure that the level that controls the spooling is aligned with the edge of the housing
6. Take a string from the new spool and feed it through the eyelet in the housing of the trimmer
(note the string is tucked into a hole in the spool for shipping, when you install it you need to free
that end from the hole on the spool and feed it into the hole in the trimmer housing)
7. Push the spool into the housing and rotate it until it feels seated and the tabs of the spool align with the holes in the housing
8. Put the cap back on
9. The string outside the housing should be 5 3/8 inches, if it is longer than this length use scissors to trim it

Overall, I am pleased with the spools - they should take me through the next couple of summers!
Ali Julia review
in general the automatic line feed system forces the use of a lot of string but this is preferable to stopping frequently to disassemble the feed mechanism and advancing the line manually.
btw - at the end of the spool of line there is a lot of line advanced, causing a lot of racket while the line is automatically cut off. this is actually beneficial because it alerts you to the impending need to change the spool.
I was wrong. You CAN use bulk trimmer line but you have to be sure to use the correct spool, the one that came with the trimmer or one of the empty spools from this product (after you use up the pre-wound line). I read some of the other reviews and suspected the mechanism that I thought was making bulk line use unacceptable. What is happening is that the pre-wound spools from the factory are wound by a mechanical process that assures uniformity in the winding process, such that line is wound tightly and uniformly - allowing the maximum amount of line to be wound on the spool. When you wind bulk line on the spool you cannot reproduce the uniformity and produce uneven winding that results in the line binding when it is fed. This binding prevents the line from feeding and eventuallly you have to open the spool cavity, unbind the line and manually feed some line.
By winding bulk line loosely on the spool you avoid the majority of line binding issues. By loosely I mean exerting no tension (IE pulling the line tight) as you wind the spool. I have found that I wind about 21' of line on the spool using a loose wind. What I recommend is that you measure out a piece of line about 21' long and tie a knot in the end (btw - the distance from your nose to your fingertips is about 3', meaning that you can easily measure off about 21' while standing in your yard and not needing to find something to measure with) and carry a pair of needle nose pliers (with area for snipping wire). It is important to cut off a length of line before you wind the spool because as you wind the line will be able to twist and thus the free end will be able to release the kinks that result from winding. Tie a knot in the end of the line and cut-off most of the excess line left after tying the knot. Slide the end of the line with the knot into the "L" shaped slot in the spool - making sure that the knot is on the outside of the spool and that there is enough slack in the line to let the knot get pushed into the spool recess (to make sure that the cover can attach securely). The line should be at the interior of the spool - ready to wind onto the spool. Be sure to wind the line in the direction indicated by the arrow stamped into the plastic. Although the length of line is less than that wound onto the spool by the factory you may find that the savings of using bulk line justifies not having to pay the factory wound spool price.
I used a bulk line sold on Amazon (http://www.amazon.com/Arnold-Trimmer-Line-Maxi-Edge-Commercial/dp/B002S47CCK?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_search_detailpage) and found that due to the density of the line that the automatic feed resulted in a fed line length about 2/3 of the length of factory line, meaning that there was very little racket from excess line being cut off by the weedwhacker. Other bulk lines should also work but be sure to get a bulk line with a diameter of .065" (what is supplied by the manufacturer). Line material density matters but this is a spec that I have never seen listed.
