I bought one of these a week ago and I like it. The opener is quite tall so will accept a wide range of cans. Reviews are very strong, and I like the red colour. I have also used the knife sharpener on the back with some success.
As with all this Walmart.com merchandise, you have to pay for shipping unless your order totals at least $35. Shipping on this can opener costs six dollars if you purchase it alone. I always wait to order until I have $35 of stuff, so I never pay for shipping at walmart.com.
