I like how easy it was once you signed up! It's very clear about what labs are available where - which makes finding your nearest provider super quick & simple!! The only downside of this service has been cost since they don't offer any discounts if used by more people within one organization compared to other services out there but worth checking them all before signing anything just incase something better comes along :) They can supply swabs / vials etc directly so no need sending samples via courier/mail anymore either as longs amazon deliver next day delivery anyway :).
