I have a smallish black dog that disappears into shadows and night an this collar is perfect to help keep an eye on him. He is so small I was able to get two equal lengths out of the collar portion and I love that it is rechargeable.

This is the best hairdryer I've ever owned . I used it awhile before placing my review so I'd know for sure how good it is . I Love how much more quicker it is then my old dryer . Also, having 3 heat settings and low, medium and high settings is fantastic ! It's like what you would get with a more expensive hairdryer. I've always wanted a medium setting and on warm . Most of the cheaper ones only have hot and cool . Also the cheaper ones only have high and low on the air flow . Plus the comb attachment is thicker and a better quality. The thing I really like is the thick round Cord on the dryer. It's not like the standard flat electric cord on most appliances, very good quality . You can't go wrong with this dryer !
