I would like to preface this review with this statement; “I do not order items that I do not intend to use myself or install myself for someone else.” Having said that;This IS a definite purpose tool that unless you are a shop mechanic that works on semi's every day, you will NOT be using this often HOWAEVER, when you do NEED it, it damn well does the job it was designed to do.

This is a pretty handy little toolThat for the job done. Easy to use. Worked exactly as intended. Can’t beat the pricing.

Great little tool to stop that pesky round pipe from rolling away from you. I used this for a shower drain adapter I was trying to install and it helped out a lot. The build quality is actually pretty good and it's easy to use and install. It's just the right size for smaller pipes and for the money I can't complain it did what I needed it to do.

We only had our Bus for a few hours when my dog knocked into the airbrake. Thankfully, we were level, and I was chalked. This solves that issue entirely and looks cool to boot! Installing it was super easy. They even had a link on the box to show you how to do it.

A great addition for our Super C motorhome. we have a large black lab that goes wild when we leave him unattended in the RV. This invention really releaves us of the air brake ever getting released by him. Great Idea!

I love knowing that this lock prevents an accidental parking brake release, especially with pets and kids around. It’s reassuring to have an extra layer of protection when my motorhome is parked—no worries about someone or something accidentally disengaging the brake.The installed ‘Stop Knob’ looks great, and they even included a special tool to remove the old brake handle and accomplish the installation. The design is awesome and easy to use; the locking mechanism simply screws down to prevent the knob from being released. I can now clean the control panel area around the parking brake without any concern about it being disengaged accidentally. Additionally, the customer service team is top-notch; I had a question about installation, and they responded to my inquiry the same day and scheduled a phone consultation to assist with my question. They provided follow-up communications to ensure I didn’t encounter any issues which made me feel extremely satisfied with this product. I highly recommend the ‘Stop Knob’ upgrade for added peace of mind for ensuring your RV parking brake is secure!

Nice touch on our motorhome and enhances the safety of the unit when parked.
