Ditto as to everything said by robo21, SamsungVibrant, and jj718. I purchased the T-Mobile gel case while waiting for the Amzer case to arrive, thinking that I would replace the T-Mobile case with the Amzer. NOT!
I also ordered a dual USB car charger with the gel case on 7/25. I was invoiced for both products, with a note that the car charger would ship on the date indicated. However, there was no date indicated. I emailed customer service on the same date that they invoiced me (8/4), requesting an estimated ship date for the back-ordered car charger. No response as of today, 8/24. So, I attempted to call their customer service number twice this afternoon. Both times the answering message repeatedly stated that I would be transferred to a rep shortly. Then, after about five minutes, another message stated that they could not "take my call at this time" and I was disconnected.
It is always a red flag when one cannot reach a vendor in a timely manner. Given these experiences, I CANNOT RECOMMEND AMZER. Note that they also use the DBAs "Moftware" and "Cosmosatellite."
