The best thing about dbMarline is that it shows real time data with all metrics, which are very helpful for debugging issues in production environments or even development when dealing w/stored procedures etc., I also like how easy its setup as well since we have only one user (you).
There's not much dislikes at this point but the price might be something people would dislike because there could possibly b more features included instead maybe? Also some minor UI improvements should help increase customer satisfaction too! We use DBMarliin from our web application where users enter their credit card information into an order form after they're done placing orders through us using mobile apps such as PayPal & Venmo.
