Background

LIF (leukemia inhibitory factor, also known as CDF; DIA; MLPLI) is a pleiotropic glycoprotein belonging to the IL-6 family of cytokines. It is involved in growth promotion and cell differentiation of different types of target cells, influence bone metabolism, cachexia, neural development, embryogenesis, and inflammation. The first exon encoding the signal sequence is alternately spliced, resulting in LIF-D, LIF-M, and LIF‑T mRNAs that produce secreted, extracellular matrix‑associated, and intracellular forms, respectively. LIF has potent proinflammatory properties, being the inducer of the acute phase protein synthesis and affecting cell recruitment into the area of damage or inflammation. LIF is also one of the cytokines that are capable to regulate the differentiation of embryonic stem cells, hematopoietic, and neuronal cells. LIF binds to the specific LIF receptor (LIFR-α) which forms a heterodimer with a specific subunit common to all members of that family of receptors, the GP130 signal-transducing subunit. This leads to the activation of the JAK/STAT and MAPK cascades. Due to its polyfunctional activities, LIF is involved in the pathogenic events and development of many diseases of various origins.

Worx very well!
Style: Lawn Edger w/(1) 4.0 Ah Battery
Worx very well. ;) More power than I expected from a 20v cordless machine. And with the 4Ahr battery it comes with, I was able to do the drive, walks, and patio without having to change batteries. I own 2 Worx string trimmers, chainsaw, hedge trimmer, drill impact driver, and leaf blower. Love them all.

will work, not for heavy duty
Style: Lawn Edger w/(1) 4.0 Ah Battery
Unbiased review. Box came heavily damaged, suspect previously opened item but not used. The contents seemed fine. Assembly was easy with directions. The battery power supply button, to dictate how much power is left, doesn't work well. This edger will work but the power to the blade is about 2/3 my electric model. I suggest using something different at first, then use this model to keep up. Battery power life is average. My opinion is the price is high for what you get. If the power matched my cheaper electric model then it would be easy to pay this price. Durability will come with time and I will post if this changes.

Right tool for the money
Style: Lawn Edger w/(1) 4.0 Ah Battery
Very impressed with this WORX Cordless Lawn Edger. My driveway have never been edged in over 30 years, this edger handled the job with ease, made a pass at one inch and then two inches. My driveway is 80 feet long, after the two passes I was left with one bar of battery power, great tool for the price. I would definitely recommend this product to any home owner that maintains their own yard.

Cute little bug that does its job. Good value.
Size: 17" (2 x 4.0Ah)
Not bad for the price. Pretty easy to set up (only user stupidity gave me any issues). Worked well for my first cut. Lasted about 32 minutes. I'm gonna give the batteries a more significant charge and try again, though I did charge for over 12 hours and the lights were solid green. So not sure what's going on there. I don't understand how "user technique" applies here, though I did hit a lot of hidden sticks. Could have burned through more energy? Idk. But it did handle those sticks like a champ! I made sure to get all the big ones out of the way, but there were some small ones and it just ran em right over good as any gas mower. I would probably play pickup sticks a little longer beforehand next time, but I was a little pressed for energy today. Anyways, irrespective of the actual function of the machine, I prefer this dramatically over either wider or self-propelled models. Self-propulsion can be very annoying when trying to get around difficult terrain or obstacles. I also enjoy the exercise! The small form factor is very nice again for obstacles or weaving between objects. It also is nice and light and easy to push. After 30+ minutes of mowing I'm not even remotely sore. I also enjoyed just getting to smell the fresh cut grass rather than belching gas smoke! I'm looking forward to low maintenance on this lil guy. The blades seem pretty well made, and I will be keeping an eye on them for wear and tear. I had a nice day outside in perfect weather with this little bug, and can recommend it if you're specifically looking for a smaller mower that lasts 30-40 mins on a charge and can deal with a push mower.
