Bad ... -More than a month to do testing even though they expressly told me a maximum of one week -I found myself with the LPG running for 3 days (forgotten turned on by those who had done it) without testing. - they say that for testing it takes an hour - an hour and a half, when I introduce myself they tell me that AT LEAST 2 hours it takes. The prices are a bit high. For me they are not professional.
