Please be very careful when dealing with **Allen Wang (Mr. Wang)** from **Alva (Linyi) Electromechanical Technology Co., Ltd. (ALVA Machinery)**, based in Linyi, Shandong, China.

In my experience, Mr. Wang signs contracts but then fails to fulfill his obligations. The machines do not meet the technical specifications and standards agreed upon in the contract. He promises to fix the problems but then stops responding.
**I have been waiting for six months for a refund and for the company to collect the defective and completely unusable machine.** Despite repeated promises, the situation remains unresolved.
If anyone is considering doing business with this company, I strongly advise caution. **Feel free to contact me via private message. I am happy to share the full details of my experience with this company, including the contractual issues, technical problems, broken promises, and the ongoing dispute over my refund.**
I want to warn other potential customers so they do not have to go through the same experience.
