I rented one for the day. It worked about an hour prior to failure of the main boom cylinder. The rental company brought me another one and after about an hour that one had the same problem as the first one.
I just returned the machine and the rental company advised me that they have had nothing but problems with the Terramites since they bought 3 of them nearly a year ago. They said that older ones were much better that they owned previously, but the newer ones are nothing but problems.
