The correct correction process should be an instant action. Most products that offer a standby mode need to be taken out of standby before you can use them, this defeats the object. <span class="a-text-bold">RECHAREABLE BATTERY-</span> E-collars that do not use a rechargeable battery end up costing a lot of money over time. This is because they drain through batteries in a matter of weeks. <span class="a-text-bold">COST-</span> Price is a huge consideration when purchasing a training collar and you typically get what you pay for. Lack of cost usually means lack of quality and an increase in the likelihood of problems arising with the device, the main ones being inconsistency and malfunctions. At the end of the day, it is your dog your choice. Expect to pay over $100 for a quality model. <span class="a-text-bold">WATERPROOF-</span> You want a dog training collar that is completely waterproof, not water resistant, otherwise it will be broken very easily. You cant predict when your dog will jump in a puddle or it will rain. Depending where you live this can provide a huge problem. <span class="a-text-bold">RANGE-</span> A dog training collar with a short range will usually not work unless they are in your garden or right in front of you. The advertised distances are in perfect conditions with no interference from things like mobile phones or anything else that can disrupt the frequency. Always think of this when you are buying a collar and the usual places you will be taking your dog. <span class="a-text-bold">MEMORY-</span> This is a feature that saves your previous settings as well as the connection so that you dont keep needing to reconnect or reprogram each time. <span class="a-text-bold">EASE OF USE-</span> Another key feature, something as simple as possible that does the job it is intended to do goes a long way. <span class="a-text-bold">HUNTING QUALITY-</span> E-collars that are designed to a hunting standard are usually better quality as they are often used in the worst conditions and need to hold up. <span class="a-text-bold">TRUSTED COMPANY-</span> Companies that you can trust will provide training videos and have a face behind the brand. They will also provide a number you can call and reach out to if you have any problems. <span class="a-text-bold">EXTENDED COVER- </span>Most companies you can trust will offer cover and put a face behind their products. <span class="a-text-bold">REVIEWS-</span> Take some time to check for verified reviews from real customers when buying a training collar.
