Very satisfied with CLZ's customer support
Had to get a new mobile phone a couple of days ago - fortunately the old one was still working so the shop assistant was able to transfer all my data across and I didn't lose my files. (I have the Books, Comics and Movies apps as well as Music.)
However they all told me my subscriptions had expired. Sytske helped me reconnect to my CLZ account and everything is now working as it should.
Always very satisfied with CLZ's customer support. Thanks, Sytske! — Gordon Davie (USA)

Wonderful software
I can't believe how long I've been using the Collectorz software! I have this mental image of me looking down at the first barcode scanner I ever purchased and being thrilled with the software that came with it -- Books. I've never looked back and have recommended your software to everyone I know who has a large collection of books, music, comics, and movies. I think I was the one who referred J. Michael Straczynski (Babylon 5, etc) to y'all.
I've just finished a major move from the West Coast of the USA to the East!
Thank Heavens for all of the Collectorz software I've been using for years as it helped me reorganize my music, videos, and books. My packers just haphazardly put books, cds, and DVDs into boxes -- what a mess! I've been slowly working on getting everything set right with the MAJOR help of my Collectorz printouts.
Next stop is helping a friend organize his book library -- including where each book is located in his home.
Thank you and your team for having created the best catalog software out there *and* for keeping it not only up to date but making all kinds of major improvements. — Wilma M. (USA)

A "Must Have" for any true collector
Easy to use, makes tracking and cataloging your collection simple. If you've ever bought duplicates, or passed on an issue you thought you had only to find out you needed it, this app will be a great addition to your hobby.
The few times I had a question, their support team was quick to reply and help me out. You can even create a "wish" list of issues you want or need, including upcoming variants. I use it every week and when going to conventions. A+++++ — Steve Wilson (USA)

Good team
Thanks for your help and keep up the good work - I have now been using Collector/Connect for many years - mainly the Book version. There is still nothing anywhere near as good. — Iain Challis (United Kingdom)

The very best in customer service
You and the team work so hard to constantly improve the software, it's commendable! Thanks for always providing the very best in customer service. — David Ferguson (Canada)

Phenomenal job
I love all of the features available though, and think you and your team do a phenomenal job with what I think is the best product ever to track music, movies and all the other product you provide. Please let your team know how appreciated you and they all are! — Jeff Kratt (USA)
