I purchased the walk behind dr pro leaf vacuum from the web site which advertised 3 day shipping. After purchase I was I informed that due to demand, delivery would take 5 weeks! Well it's been more than six weeks and after contacting CS my projected delivery date has morphed into 2 months. If it snows before thanksgiving I'll never use the vacuum this year. I've purchased 2 machines previously from DR with various performance issues. This was an obvious scam for advance orders before actually creating inventory. This will be my last purchase.
