I love that LC is visible in the dark, I don't need to get up at all to use it.I just roll over when the little alarm sounds. I like that it's rechargeable battery is good for 10 years as oppose to 2-3 with Pearly. I like that red blinking light to know when I ovulated and I often look at the "forecast". And the % year warranty cinched it for me. I bought my LC from natural methods using their installment plan.
