Think it's far too large/heavy duty for my requirements. Also has 2 grab points where as other models have 3.I need a device to get into narrow difficult to reach places. This model is heavy duty with a large pushbutton and quite large diameter along length of mechanism.It might be suitable for car/tractor/marine mechs/engineers but if like me you work in areas where access is often restricted this device is unsuitable. Unfit for my purpose (Aviation).
