Great for 2 or 4 people which is fine for our needs, 6 would be overcrowded. We are using as "plug and play" so did not upgrade the electric, knowing this means the jets would not be a strong as they could be which is also fine for our needs.  Works well, did not make a major impact on my electric bill, keeps warm and clean BUT does cool down during prolonged use.  We put a hard top canopy over it. Perfect for my needs!
