"Officials who used this device found it worth the price. But some people see the price as too high." When the GT200 scandal first came to light, the equipment was tested by the National Science and Technology Development Agency (NSTDA) and it found that the GT200 consisted of two pieces of plastic and lacked any electronic components, as was advertised in a brochure distributed to potential customers. According to the Bangkok Post, "Because it was so thoroughly and risibly cheated, the army has never fully accounted for the GT200's cost, in baht and in human lives. Rough estimates put the economic cost at around 500 million baht." A related case—that of the Alpha 6 drugs detector—was declared "closed" in May 2018 after 10 years of investigation. Three minor officials are deemed responsible for the purchase of 493 of the "worthless [Alpha 6] boxes" at a cost of 350M baht. The British scammer who sold the devices to Thailand was found guilty of fraud in the UK and imprisoned in 2013. The Bangkok Post fumed that, "The disappointing and unsatisfactory outcome of this astoundingly long investigation shows up the enormous failings of the anti-graft commission." As one columnist summed up the investigation, "And you'll never guess how many government ministers and army chiefs (currently in government) the NACC found responsible. Whoa! Yes, 'zero' is correct.

Altogether the payouts amounted to just over one billion baht. The NACC, investigating the case, has been accused of mishandling it, with no bribe-takers identified nearly two weeks after the British firm's 17 January 2017 admission to a UK court that it had bribed Thai Airways and Thai government officials to win engine orders. In 2018 Rolls-Royce and Thai Airways signed a deal making Thai a Rolls-Royce maintenance hub. The Bangkok Post reported, "The press release announcing the new tie-up made no mention of the scandal revealed two years ago showing that Thai government officials had received Rolls-Royce bribes to buy the firm's engines. Thai and Rolls-Royce executives ignored the connection. The government has taken no action and the National Anti-Corruption Commission (NACC) has been silent on
