So far so good. Easy to install and with the three adjustments it works great. Heavy steel outside door is no longer slamming. Commerical building with roughly 25 people.

This item is very good quality and comes with everything you would need. The installation instructions are not very good as of 2/12/2024 purchase. I had to email the technical support and they let me know that they in the middle of creating a much better instruction manual. I did however finally figure it out on my own. I don't think the person I emailed was a mechanical person. This is the only reason I didn't give 5 stars because of the poor install instruction and help I received. The opener works very well and has lots of adjustments so you can fine tune the closing of the door. Knowing this gets installed now, I would definitely buy this one again.

Once I figured out how to install it properly, it was a cinch. Love that it finally came with the wrench for adjustments amp; it's all the same size now to work with the wrench.

I'm here apologizing my late correcting feedback, for my forgot; when I first ordered this product, a wrong part arrived,but after I left a complaint online, the seller contacted me immediately offering technical help, and he also sent me another one which works much better ---to better describe,works perfectly! I'm very thankful to this seller and will recommend him to everyone I know who needs a door closer!
