I recently purchased the delanclip fusion pro, it is absolutely amazing, especially for the price. Very precise head tracking simple and easy to set up and the customer service from Tomasz is excellent. I was worried my delanclip wasn't charging properly, dropped them an email and Tomasz replied within 3 hours and on a Sunday! After their guidance I found out the charging was just used error on my end. A 5 star experience all round, definitely worth your money. And local to me which is a bonus!
