Although it looks like a nice little product, I could do without the loud motor noise that is emitted. The unit would work fine if you didn't need to listen for it. It also is not very loud. I did test the suction power though by using my hand vacuum cleaner with which I got good results. All in all, I'd say its worth $17 as long as you don't mind being aware of sound when vacuuming.

Ex Output:

This was my first attempt at a diet or exercise book. I bought it in paperback for the price of only $3.99 and thought I'd give it a try. The format itself is easy to follow, though there isn't enough detail on each recipe -- if you don't know where to start, as I didn't, it's pretty difficult getting back around to it. The actual recipes themselves are not that exciting. I've made them several times since receiving it; they taste alright, but nothing too special.

Ex Output:
Good Review

These were very expensive for 2 pens. They don't write as smoothly at the Zebra Mech Ball Grip Roller Ball, which is 1/2 of the price or more! If I am going to pay $2 per pen, the ballpoint version would be worth it. The only thing that makes these pens unique (other than their low price) are they have a cap on them. Don't waste your money like I did. It may work out for some folks, but it isn't working in ours or anyone else's household.
