Keeping my home and family safe- FM502

Customer review by Blake Al

5.0 stars by Blake Al

I Purchased a DIY Driveway gate from mighty Mule/GTO called the “St.Augustine.” The gate itself not only makes my property look nicer, but also gives me he peace of mind to leave my family home alone when I leave town for business. The gate opener is dependable and was easy to install with the help of the YouTube videos on the website me and my son had it up and running in no time. If you are looking to protect your home and family, I highly recommend considering a driveway gate!

This is the 2nd one I have had in 20 years. You won't be sorry. Keeps unwanted guests and sales people out. I have the dual model and it works great. You must get Automatic Gate lock with this dual opener. People will try to seperate two gates to slide through. Great unit "Outstanding"

Excellant customer service

Customer review by Hubert

Discount Gate Openers brings back customer service from the old days when customer satisfaction is the number 1 objective. I bought the MightyMule 352 but because it was out of stock, DGO immediately upgraded me to a 502 without charge so I could get my order on time! And later, I found I needed a pair of brackets for my push-to-open application, they shipped me the brackets immediately with no questions asked! I am very happy with the ways they handled their business. Buy from them and you won't be disappointed. I will have a follow up review once I get the gate opener installed. Cheers~~
