I really enjoy how easy it is for our team members across multiple teams in several locations around Canada as well as out-of hours support staff - all with different schedules/time zones! They are very responsive when we need help (which never happens) but if an issue arises at 2am they will be there until 9pm that day :) The biggest problem right now has been working through their API limitations which have impacted some functionality within my business app; this seems not likely going forward though so everything's looking good currently! If you're considering purchasing firecracker make sure both parties communicate expectations up front about what can reasonably expected before signing anything off ;) Also ensure you understand exactly who supports each other during those time frames outside normal office times etc., especially where data integrity comes into play such security concerns. We run an online booking system called "Priceline" It integrates seamlessly between 3rd party sites including AirBnb / TripAdvisor allowing us customers access via one simple.
