Has anyone tried the Timekettle translation devices? If yes what model and was it in a one on one or group setting? Love some feedback as they seem to get good reviews.

I just extended my SETV for 30 days at the Jomtien Immgration, and ask to apply for my 90 days Non O Visa over 50 (retirement). I had my T86, T7, Passport info page, Visa/stamps page,

2 photos, hotel lease, 2,000 baht and Notary Income letter from U.S. Embassy and translated into thai.

The Immgration officer said i have to take the Notary Income letter to Bangkok to the Ministry of Foreign Affairs to get it certify (Cerification). What all do i need to take? Anyone know the cost and can i do in one day? Do i need that translated into thai also? Any feed back would be appreciated.
