Beware of Wolverine Technologies.
After ordering parts to build a centerfuge, i ran across a post on another forum from a guy who had waited 5 weeks for his complete unit. He said they could not be reached by phone and were not returning any messages or emails.
I decided to check on my order. My card had been charged the day I placed the order but after 2 weeks I still had no parts. I sent and email asking for an expected ship date with no reply. I tried to call and got a voice mail box that was full. I tried the owners cell number and got a message that said to "leave a message if you want but at last count there were 917 messages in my mail box". I tried a text message and no reply.
I sent an email asking him to cancel my order and then called my credit card company. I was able to get my money back from the credit card company but I'm sure they got screwed.
