I recently purchased the Havaheart custom wireless for 2 dogs. After reading numerous reviews and looking at multiple brands, I finally took the bait and bought Havaheart custom wireless. I’ll admit it was not cheap and I was EXTREMELY skeptical! I was skeptical about a wireless fence to begin with, especially with two dogs that were 7 and 9 years old and had never been fenced in before. Due to moving to a new state, the laws changed and I needed a fence ASAP. However, I found it really EXPENSIVE to try and fence 10 acres and with a limited budget, well…I looked for other options. So I started looking for alternatives and after doing all the research, wireless seemed right for me. Thanks Havaheart this fence is exactly what I needed!
