I recently ordered this tool kit at an extremely reduced price.
While I am confident about the general quality of those tools I am quite reserved about the spring tensioner included in the kit. In other forums people advise strongly against such types of compressors and urge people to either get a professional compressor or let an specialist do the job. This brings me to my question:
Are those two-part spring compressors in generally reasonably safe to operate? While I understand that with enough carelessness / bad luck everyone is able to hurt himself I see a above average risk in these type of compressors slipping away the spring. Should I be happy about the rest of the kit, throw away the tensioner and bring the car to a professional should ever the spring needs to get removed OR can I use this tool, given enough precaution?
Background information: The intended use would be some vehicles in the 1000-1500 kg class. Front suspension are always McPherson-type struts. Rear suspension would be twist-beam type with separate dampers and springs. I aim to repair (as far as possible) everything car-related on myself, however I am not willing to unreasonably risk my safety/health.
Edit: Some recommendations on needed precautions would be highly welcome
