Review title: Stopped working after two months Product review: We thought this would be a good, inexpensive card shuffler since the Bicycle company also makes decks of cards. Wrong! One side of the shuffler was always pretty sluggish, making the shuffling process uneven. After two months of only occasional use, the other side quit working altogether. We actually took the thing apart to see if it could be repaired (because how many card shufflers does a person really want to purchase), but the plastic gear had slipped and couldn't be moved back into place. Now it's going to the recyling bin. Sure, it was inexpensive, but that doesn't justify the fact that it's basically junk.

Product review: I had been using this product for almost a year now. I feel this product is too mild to remove any kind of smell completely. And to constantly keep adding water in it is a pain especially in summer time.The price is too high to justify the worth of this product. Neither there is any scientific reason to back its claims as a smell killer.If you want to get rid of the smell in your car then first get rid of the source of the smell. The primary source of foul smell are smoking in the car, eating smelly food in car, spilling food and drinks on upholstry, pets, damp carpet on the floor and finally a dirty cabin air filter. Cabin air filter has a life of one year and should be replaced periodically. This filter can be dirty and become the source of mould growth. The carpet should be dry, if not allow it to dry by removing floor mats and allowing air flow by opening windows.Try and avoid smoking and eating in car. Promptly clean any spills. This way you can eliminate smell.

Review title: Porter Cable dovetail jig Product review: I've used this jig about ten times now and have finally figured out how to work it. The instructions are quite adequate, but it takes some practice to get really good cuts. I haven't been able to cut dovetails on plywood; the bits just splinter it to shreads. But it works well on pine and hardwoods. One problem is the inclusion of two bits (for the mini template) with 1/4 inch shafts. My router is set for 1/2 inch bits, so I would have to buy and install a 1/4 inch collet or buy two additional 1/2 inch bits. I will do the latter, but the jig should come with bits of consistent shaft size. And the buyer should have the option of selecting the size bit shaft he prefers.

Review title: Don't buy it Product review: Audio quality is unacceptable. Looks nice, but can't play sound from a nearby strong station in the Bay Area. We bought two, and will be returning them.
