What is the difference between Innotek, Petsafe, and D.T. Systems?
• A. The systems that we carry are all reliable, which is why we offer the 30-Day Money Back Guarantee. The Innotek line is the most extensive, and offers the most discrete differences between the collars. The D.T. Systems collars tend to offer the widest range of intensity levels. The warranty on the Petsafe collars is usually the longest, since its a lifetime guarantee.
