This seller uses a name similar to a reputable company but uses a bait and switch method of selling products. I ordered RTX-6 but was sent RTX-B. What is the difference in a number and letter? About $20 on this item, possibly more on other items. At this sell price you are not getting a deal but paying average price. I RETURNED THIS PRODUCT! Boycott this seller!Black & Decker RTX-6 2 Amp 3-Speed Rotary Tool with 30 Accessories and 2 Spring Clamps
