dont get me wrong - i love being cheap
but this work is what you get money ... so your tools should be the best you can get ..
Buy lush!2 or 3! (not the first one!) and get it within a week .. you start doing money when the one from Alibaba is still on the road (up to 6 weeks)
And dont forget - buying in china - you have to pay taxes and fees .. so at the end - the difference is not so much.
one year warranty - that could come handy - forget that with china - Lovense´s one is a nice to have (used it already)
finaly - at least 3 nice tools for our work - all the same company and app .. thats comes handy too
at the end - for the little more you spend - you get a big plus on a "pro" working tool.
