Plastic Pro-Training Dog Collar - Large - 21", Black, 8 Inch, 3 Inch

Very nice product, I think it’s worth every penny spent. It’s a good quality and sturdy product

So I use this with most of the dogs who are heavy pullers on the walk. The Collar is strong enough and should be used on dogs who pull frequently and the owners have no control. A few things I would like to specify. This collar is particularly for large breeds and not small ones. the second part is this will not work on dogs who are sensitive from their genetics. I got 2 dogs in my training who would keep yelling unnecessarily the moment there was even slight pressure. So check your dogs temperament before buying this collar.

The product is good for those who are looking a less expensive alternative for good quality prong collars. Or looking for something that is less "traumatic". However, one needs to understand how exactly prong collars(and this product) are required to fit and to be used. Just putting this on the dog and hoping it will behave will lead to poor results or even worse behaviour. TLDR: Product is decent for the price. But owner needs more training than the dog before using any such products correctly.

I doubt the authenticity of this product.

Very very third class product and Amazon service is very bhangar third class 15 days plus hogaya abhitak mera refund nahi aaya or no reply Ekdam bekar he ye amezon . costumer service is very poor Amezon vale froud he

It is not much effective for dogs, especially large breeds like a lab. I can say this because when my dog was under training period with a dog trainer he use to use the original stainless steel prong collar. though that cost around 4 to 5k. however, buying this StarMark Training Collar is not worth it will be better to buy the stainless steel prong collor. I made the mistake of having 1k for this. don't buy this item if you don't have small breed of dogs.

Really a fantastic collar for easy correction of your fur baby without harm or pain
