I received this product in exchange for my honest review, I wanted to try this product out because we do a lot of camping and hiking and needed a way to charge our phones when away from home , I was very pleased with the look and feel of this product, it's well made sturdy and perfect size, when I received charger I plugged it in and charged for about an hour , I then plugged in my lg vista and my husband's Samsung that were almost dead , I was amazed at how quickly it changed both phones to 100% over the next few days we used it several times on several different devices and didn't have to charge it until day 3 , I am thrilled with this product and highly recommend not only good to have when out and about but would be great for emergency situations like power outages

Don't waste your money! It's cheap because it won't help you. Spend the extra money to buy course specific study guides.

Do yourself a favor: download the sample, skip to Chapter 2 -- which is where the back story starts getting injected after a kickoff on arrival at the massive alien spaceship -- read the inanity within, and save yourself from even mildly wanting to read about the silly characters' space adventure. Cue the predictably stereotypical NASA male nerd: "I'm here to recruit the World's Greatest Linguist for a top secret space mission, so I better not say anything stupid because I totally have the hots for that hottie. Who knew such smart chicks could be such hotties?" Cue the unflappable, driven academic woman: "I don't have time to stop walking while this horny nerd pesters me, I'm too miffed that my brightest female grad student is about to throw her career away on marriage and babies. But I guess I'll pick up coffee and drive out to the middle of nowhere with him so we can talk more privately about whatever he wants." Nerd: "So uh, this is all classified, so I'm going to need you to sign a nondisclosure agreement later (if I even remember to give it to you), but nevermind that. The Roswell UFO crash really happened, and we're going to go explore their giant mothership way the heck out in the asteroid belt." Superlinguist: "Huh. Interesting. I'm not at all astounded nor do I even think you've watched one too many X-Files. But anyway I'm not up for the job; like Ted Striker in Airplane!, I can't get over the last time people trusted me on a Doomed Voyage. Bye." Nerd: "D'oh. I just gave out classified information, AND my fellow nerds are gonna think I hit on her."
