Ultra-Small Dog Shock Collar for 2 Dogs - 1300ft Remote, 198-Level Control, Waterproof & Rechargeable Training Collar for Small (5-15lbs) & Medium Dogs - Perfect for Obedience Training, Bark Control & Outdoor Adventures (White/Black)

I'm super happy with this dog training collar set. It includes two collars, both controlled by the same remote. I only have one dog, but this is super useful as it allows me to charge one collar while the other is in use. While it's marketed for small dogs, the collars are large enough to fit my medium-sized mixed breed, Mia.The best feature is the vibration. It's strong enough to get Mia's attention without being harsh. I've found that the vibrate function alone is effective enough not to need to use the shock feature. Normally, a beep is enough to do the trick, but the vibration is perfect for more stubborn moments. My dog responds quickly, and I feel good knowing I don't need to inflict discomfort. There's even a button to lock the shock feature to avoid accidentally using it.The remote is easy to use, with easy-to-understand buttons for each function. I've only had the collars for a few days, but the battery life seems solid. The range seems good, too. The collars are highly adjustable, and the receiver is way less bulky than other models I've tried. The small, low-profile design doesn't get in the way or seem to cause any discomfort.Overall, I'm super happy with this set. It's a great value since it comes with two collars, and it does the job as advertised. If you're looking for a quality dog training collar that won't break the bank, this set is definitely worth considering.
