The Shark did the job great! I did learn a few things - clean it out often (my goodness it sure picked up A LOT of dog hair!) because the suction got a little slow and I discovered that the little dish that holds the dirt filled up FAST - that's a good thing, but I do have to clean it out every time I use it. Did a great job on my tile (even picked up dog food). It doesn't do very well when used on the sides so you have to hit the dirt head on. VERY lightweight (so my 9 year old can do the vacuuming now!) Excellent swivel action. Fits very nicely under the dining room chairs, behind the toilet, etc. Quiet? Well, quieter than my vacuum cleaner. Oh, and it even coverts to a hand vac which is great on stairs! For $30, I thought this little guy was very worth it! Is this product review negative?

Ever Review: I spent two months in Spain and Portugal this Summer with Let's Go as my only source of information and it constantly let me down. Times, prices, phone numbers were often so wrong that I eventually gave up trying to plan anything in advance and ended up relying on my broken Spanish to keep me alive and on schedule. The maps only show the most expensive and most touristy parts of town and the restaurant and club reccomendations seem to have been paid for by the establishments and not based on merit. I stayed with friends in Granada and Lisbon who wouldn't be caught dead at the clubs Let's Go gave the thumbs up (their highest reccomendation). If you want to meet other tourists with the Let's Go guide, then buy it. If you want an authentic enjoyable experience, buy a different guide Is this product review negative?
