Couple issues which will probably cause me to request a refund:
1. I had no idea the blower needed to continuously run which makes this impractical to run indoors.. I would estimate the noise level almost at the level of a quiet leaf blower.. which is too loud for indor use in my opinion.
2. Unless I have a defective product, the sides of this house are not effective as a safety barrier for all but the smallest players. This creates a safety hazard that will make it hard for me to keep the product.
