I had a problem whereby I could only achieve 100mbs on my home PC, despite being able to achieve over 250mbs through the same router using 5G. Shakeeb Fouz walked me through numerous checks & tests and confirmed that althoug my cable router to pc was rated as cat 6,it was not heavey enough. I subsequently purchased a different cat 6 cable and now I can achieve the desired 500mbs on my PC. Well done Shakeeb.

I was struggling to find a good magnesium spray to use before bed. I was taking magnesium supplements but I needed an extra boost. This product showed up and it was perfect. I quick spray on the soles off my feet before bed after my shower and it guarantees a deep sleep almost every night. It’s now a permanent fixture on my bedside table.
