Hi eLuk,
Big Time Wireless is one of our verified and trusted suppliers in the SaleHoo directory. Although none of our members have left a rating or review about them, they should be safe to use.
If you have any further questions or inquiries about their products you can always try calling them through their toll free number 888-924-4846 (if you are based in the US) or 917-267-7740 (If you are located outside the US).
Hope this helps.
And if anybody has bought from this supplier, kindly speak up, your opinions/feedback are much appreciated!
Cheers :)
