Avoid "fitnessresearchgroup" at all costs. This guy's/gal's a completely unprofessional jerk. We bought and paid (via Paypal) for an item on 4/2. We waited. We never received an email from seller. There was no tracking number information available via our "My Ebay" page, as there is when sellers ship via Paypal Shipping. We emailed asking if the item had been shipped. No response. Waited a few days then emailed again. No response. Waited a few more days then emailed again. No response. Finally the item showed up & it had been POSTMARKED 10 days after we paid. TEN DAYS! We left the seller NEUTRAL feedback, which doesn't hurt his numbers in any way. It was not rude in any way - just stated the facts. He/she left us NEGATIVE feedback.
