CRL CRL7262 Heavy-Duty 90 No Hold Open Overhead Concealed Closer Body Only

Fits and Works well but there's no adjustment on opening. You need some effort to pull door open. The door closes and latches at a good speed.

I received this product on 7/6/2022 and found it broken (liquid came out) on 8/8/2022; just a few days passed the return date. What kind of quality for the product which is supposed to use at least several years?
