Yes. I have been using this service for more than 5 years now, can't complain. The owner is a very nice guy, well experienced in setting up the companies in the UAE.
As for the service in question, I never got any problems with them. To setup the account, a passport or ID copy will be required. I get email notifications about mails or parcels. Mails letters are scanned and they can open and scan the content on request. Parcels are pictured.︀ Mails have to be addressed to their PO Box with unique suite number assigned to︁ your account. So in theory it allows you to address mails and parcels without revealing︂ your name on them, as long as the suite number is mentioned, it would be︃ assigned to your account.
They have also received parcels on my behalf exceeding $1000 value,︄ no issues. They do exist under this address mentioned, as I visit them from time︅ to time for mails pick up.
However if you require parcel forwarding service from UAE︆ to elsewhere, I would consider
Shop&Ship (by Aramex) which will provide you with UAE and︇ 20+ countries unique address and forward your parcels supported destinations. It may simply be cheaper︈ than using FirstPostBox and a courier company, although I am not sure what rates do︉ they have with the courier companies.
