Ordered a set of recovery disks for my HP-150. They were sent out promptly, and I received them within 5 days. Before they arrived, I found my existing disks, so I had no use for them. I contacted RestoreDisks.com, they gave me an RMA number and I promptly sent the package back. They promptly refunded my money to my PayPal account. I gave them 5 stars because refunded me the money even BEFORE they received my return. I followed up via email immediately after sending the package, and they responded they would apply a full refund within 24 hours despite not having received the package yet. I thought that was excellent customer service.
As for the quality of the product, I have not real comment since I never tried it. However, since I found their customer service was excellent, I can only assume the quality of their product would be equally excellent.
