So I am stuck between the decision of the Dogtra 3500 NCP or the Tri Tronics Classic 70 G3. I would like buy an e-collar that is going to last for the next 5-10 minimum. I am hesitant to go with the TT because if the Garmin buyout and have been doing research on here and seen a lot of bad TT review but good ones as well. I have seen pretty much nothing but good reviews and post about the Dogtra 3500NCP. I do like the tube style of the TT transmitter also but the dogtra seems to have more functions than the TT. Which would you guys suggest or have. If you have one of these, please tell me what you do and do not like about each.
