What you are paying for is the idea plus marketing costs and if you dont make a quick profit someone else will reproduce a similar device ane sell on Ebay for a fraction of the price. I dreamed up a similar device but with a small inflatable balloon , I had seen surveyors use it to test drains by sealing them and then pressuring to detect a leak. If you decide to patent manufacture and market an idea you had better get it right or you will soon run out of money.
