Long time user
I have been using CLZ for my 2,700 book collection AND for my 1,300 DVD/ Blu Ray collection for over 15 years. With the size of both collections I was often duplicating purchases of books and disks until I started using CLZ web and mobile software. Both platforms were easy to setup and use.
Over the years their developers have asked for us users for input on how to improve their products. The upgrades the have made makes it more versatile and efficient. Whenever I have a question they respond immediately and in this day and age that is something special.
I highly recommend CLZ products to any collector. You will not be disappointed.

My entire collection cataloged
For the first time in years, I will have my entire collection cataloged. I had a question regarding a minor issue and customer support responded quickly and was able to help me out. I would definitely recommend.

Worth every penny
This app (and the company behind it) is incredible. It is constantly getting new features, fixes, and improvements. This makes it easy for me to catalog and track my collection (and the missing pieces I'm hunting for).

Kindness and professionalism
Thank you very much for your kind and generous support.
I was honestly surprised — and deeply impressed — by your decision to assist me through a version upgrade, especially considering that my original purchase was made more than 12 years ago.
In today’s software industry, it is rare to see such thoughtful and customer-focused support for a legacy product. Your response truly reflects the values and integrity of CLZ as a company, and I am sincerely grateful for your understanding and flexibility.
Thanks to your help, I can continue managing my music collection with peace of mind, and I truly appreciate the care you have shown in handling my case.
