I bought the pocket Silver Puppy years ago when nothing would help my cat Baby. It served its purpose and was a beginner generator but now it is in need of help. When contacting the owner multiple times on why my CS is turning dark he refuses to answer. As you know customer service is so important. He shipped it to Jordan for me and that was good but told me not to buy any extras to measure the CS and I wonder why now. So would I buy or recommend this to anyone? NO.
