## Customer Reviews

### ⭐⭐⭐⭐⭐ Sturdy and well built
*by T***S on March 15, 2014*

I purchased this to replace a Reese TowPower Professional grade hitch lock that fell apart after three months of use. This Curt lock works smoothly and feels very sturdy. The end cap fits perfectly and should not easily come off during normal use. I am pleased with this purchase.Update: 1/9/15We have used this lock continually for about a year now, most of the time to protect our decorative hitch cover, but also anytime we put the receiver in the hitch. This lock is still strong, rust free and works smoothly. I actually use it to remove the cover frequently, as we use a dog step in the hitch or carry our bikes around. The rubberized cap has held up very well. We live in Southeast GA, so we do not experience the heavy winters of those in the northern climes, but for our needs down here, this has been and continues to be a great buy.

### ⭐⭐⭐⭐⭐ Feels solid and secure
*by N***E on June 25, 2022*

It feels really heavy duty and works well on my 2019 Tahoe. I have had issue with the other pins fitting correctly because of space. This spins around so you can easily unlock when installed. I also like the rubber cover to protect the lock portion from water.

### ⭐⭐⭐⭐⭐ Made in USA!
*by D***D on November 5, 2013*

Perfect. Made in USA! I only trust 'Curt' when it comes to towing. Reese is good, drawtite is good, but I am a Curt guy. It is simple and works like it should. I was thinking about ordering one of the nicer ones that fits snug and doesn't have any slack, but I didn't want to spend that kinda money. This is simple and cheap. It comes with two keys. I have maybe 2" of slack so it can slide back and forth. The lock works nice. I am not worried about somebody stealing my pintle hitch. I am very, very happy with this hitch lock. I would recommend this to anybody.
