As only one wall bezel came with our iRobot we decided we needed 2. When we looked at the price we were amazed. When they saw the price, they decided not to take it. It's ridiculous to ask so much for such a small device. Due to the inconvenience of only having one barrier, we decided to "bite the bullet" and buy one. I am very outraged by the really high prices for items that are needed by the population.
