Halo Collar review: Halo collar is a loser

We were so stupid buying halo collar 2-times our dogs ran right through the marked fence. We live near a very busy highway. We did everything the videos showed us to do, during the training period. We have had this for about 1 1/2 years and still no results. We paid 599 x2 1,200 bucks and also pay a monthly subscription fee on top that. Tracking the 2-dogs it does show the location but it very fuzzy (i have a new I phone, so that is not the problem!) Halo is the problem! DO NOT "DO NOT BUY THE HALO COLLAR" We almost lost 2-dogs because of halo they would have been KLLED if we did not go after them. Here is what halo said when I called them (sorry) (good luck trying to find their phone number no 800 number 214 area code. Halo the trust with your company is broken!
