From start to finish, the team at My Amplifiers, especially Anna on the sales side, and Marina on technical, have been wonderful. I bought a NS1100GSM+4G signal booster with no real idea as to what it could do or how to set it up. Firstly, Anna helped me through the buying process- note the company is based in Cyprus, with office in Gibraltar, so at first I was a bit worried. I need not have been at all. The only thing on the sales side was that in fact the equipment is shipped from Hong Kong and so the courier required me to pay a nominal - less than £20- for import duty. It was a pity the courier did not actually tell me what the product was that I was being charged for so I had to make a few assumptions. Lucky I don't import many things from Hong Kong! Anyway, I told Anna what had happened and she immediately arranged reimbursement, so top marks for that alone, but Anna had also been really helpful when I explained I was buying the booster kit for a remote forested location in France. After delivery, I have needed to check up a few things, especially since on initial installation I experienced what Marina in Tech support described as "excitation". Well not me exactly, it was the equipment!. Marina kindly explained what it all meant, and what to do and it was perfectly simple to remedy the problem by better distribution of the antennae. She also explained how the attenuation of the signals can be adjusted, again something that I being non technical had no idea about. I am delighted with the level of support from my amplifiers, and would certainly recommend people not to be afraid of dealing with this offshore business. Really nice people! I have read the review by K Fahad about the equipment being a Chinese copy of a Nikrans device. I can't comment on that, but my kit was definitely advertised as Nikrans so I hope it is, but anyway, it's working brilliantly.
