GSMPerformance Opiniones 

Customer service is abysmal. Only thing saving a 1 star is the quick refund.

Once you place an order with GSM, expect a lot of emails telling you about how they deal with loads of distributors and hand check all orders for quality before sending, which sounds good, but the more you read the more it sounds like they hold no stock at all and are making excuses for the time it will take to source and ship your product. Which is exactly the case!
If like me you receive these emails but phone them just to ask for a very rough ETA for your order (because you never receive one), then expect a response like, "could be 24 hours, or it could be 3 months". That ridiculously unhelpful response coupled with the bluntness and down right rudeness of whoever it was I was talking to (Gareth or Cameron) made me feel like it was my fault for asking a very simple question. They even said I called too soon, when in fact they'd had my order for hours!

Ultimately, my experience has resulted in this review! I don't usually leave negative reviews for SME's, but my advice to those who come across GSM would be to think twice before ordering from them, unless you call to check lead times first.

On a side note - their competitor, Demon Tweeks, managed to ship the same products (I ordered from GSM) on the same day, and deliver them within 24 hours! I got order tracking details and an ETA during the process too. Now that's service gents!

Fantastic experience ordering with GSM Performance. Garreth was super friendly & helpful running through all my questions and to offer me advice on the best options. My order was shipped out next day, was well packaged and arrived quickly, each step along the way I got regular updates. 5* seller, highly recommended
