For what it is designed it does the job well. Solidly built, it's padded on the inside to fit the dimensions of Helix LT so it does not move and tumble, it has rooms for cables etc. and there are four "legs" on the bottom side. The legs alone, not the weight of the whole thing (case+helix = 13.5 kg), is really solid and has high friction coefficient so the thing is not sliding on the floor when you press buttons in the heat of the action, dancing arround etc.
The case is somewhat heavy even without the Helix unit inside and closing the latches is a matter of skill that comes with time. It has to sit perfectly to close and you need to 'feel' when the hook of the mechanism is in the correct place to close. Those would be the "negatives".
Overall I am very pleased with the product and the service.
