Negatives; very complicated... A local man had to help out. about half the washers weren't working. the large load washers are unusable because you can't read the dial display. our first dryer was cold, so we had to pay again for a second attempt. positives; credit cards or cash. once we got the dryer working, it dried very quickly. detergent added & smells ok. free 2 hr parking opposite. dk133!
