Numverify alternatives

I genuinely do not understand all these good reviews of Kaspr. Look it looks really nice and is well laid out, but that is where it ends. It does not do what it is set up to do. I use another Chrome extension providing the same service and Kaspr performed horrifically. Out of about 100 profile views I think it found maybe 2 mobile numbers, where as my current provider found literally loads. It was the same with email addresses. It found more emails than it did mobile numbers but not by much. The prices they are trying to charge for a service that does not work is beyond me. It is a nice looking platform but they have a LONG way to go to even get to semi decent standard. Sorry Kaspr but this is true
