Great product
Style: Alpha TT 25
It's a garmin product what more can I say. Tracks well and good battery life

Great equipment, but learn from my mistakes
Style: Alpha TT 25
Works great, takes a little time to connect to satellites so expect a few minutes waiting around. Wouldn't recommend using it in the water, rubbed my dogs deck raw lost all the hair around his neck from the collar not the prongs. Once I figured it out we love it, will buy again for my next dog.

I haven't lost a dog yet!
Style: Alpha TT 25
I love the TT25. I have purchased 4 of them. Fortunately they're very durable. My female beagle jumped in a pond and swam across rather than go around like the other 3. Very easy to use, and works as it says it will. The only thing I wish is that the beeper was louder.

Impressive technology for keeping track of your pooch
Style: Alpha TT 25
This is a great little collar and a much better replacement than the TT 15. I like how it updates when it’s plugged in and paired with Wi-Fi and I like the different lighting options. And probably most importantly the hound hasn’t complained yet about it either.

This is another great product from Garmin. I’ve used their products for years and this one meets all expectations.

Excellent training Collar and very accurate
Style: Alpha TT 25
I paired this collar with a Pro 550 Plus and they work excellent together for training with my German shorthaired. Very easy to pair and use one you learn all of the functions. The layout of the low/med/high stimulation is easy to get used to for training and the correction of bad behavior and provides peace of mind when working with a young dog off leash. The gps is very accurate down to the foot. The light feature is awesome at night and is very bright. The battery in the collar long outlives the remote. Used in some heavy rain and worked without issue. I have only paired and used one collar so far but highly recommend regardless of the price. ... show more
