I have used just answer several times. They provided very good legal advice from qualified experts regarding landlord tenant disputes, filing dates, and small claims actions for Pima County, Arizona. The expert researched specifically Pima County, since different rules and procedures apply at different Counties throughout the country. The qualification comment is that I had received an "educated guess" person (not from an attorney) on the need to file certified mail return receipt verse US mail.
So make sure you are always dealing with a qualified expert. Not someone who is NOT qualified and will ONLY give you a "educational guess". Just Answer homepage indicates they do background checks on their experts, so make sure you get a qualified individual by asking up front their background and certification, license, degrees, training, etc. etc. Etc.
BUT... overall my experience has been very good when it came to excellent answers, qualified people, promptness in reply, and also immediate customer service and membership response if there were any problems. For that reason the 5 stars review... Combination of qualified experts, accurate responses, fast timely responses, excellent customer service with any problems and excellent membership support.
