Great product overall, receiver issue is the only downfall
Purchased the SDF1A a year ago and have had no issues with exception to the receiver units breaking. I have two labs that wrestle around a bit, but nothing that should damage these receivers the way they were. First one broke in half near the seem about 3 months in and the second one lost a corner about 6 months in. Luckily I was able to part out the other collar to repair the second one. I purchased through Amazon and didn’t think a warranty was an option. Called customer service on a whim to see if there were alternative receivers, or if the current ones had been upgraded. They were very informative and stated they are aware of the issue and always working to better improve their products. I give two thumbs up for customer service, which is rare these days. I’ll stand behind a company that backs their product all day long.

Great Product
Ive had my system for almost 4 years now. I have a Doberman that roams the yard and never leaves thanks to this unit. Very easy training using the steps provided. Most of the time I don't even have the box plugged in. He will NOT try that fence. Thanks Sportdog.

Screw holes for the battery broke
I have had the collar of about a year and it has been fantastic. I work long days so I let my pup roam the yard when I’m at work and she absolutely loves it. The only problem I have with the system is the collar all four of the holes for the screws broke over time and the last one broke when I was at work. When it broke the cover fell off to wear the battery was just dangleing and my pup must of went nuts and ripped the battery and the wires right out. Everything was great except that and I’d hate to spend another 100 bucks on another collar
