Solid, dependable, and simple as pie! My last IMP lasted 35 years, through gigs, rain, abuse, dusty barns and beer soaked stages. Finally gave up the ghost, so I bought another. Likely they'll bury me with it.

just set up the di box today; running my guitar through di box to mixer to alto self contained speaker; great sound;

I bought this to send signal from a guitar to a mixing board about 110 feet away. It worked without any degradation and the signal was more than clean enough for recording. Low impedance XLR output makes it easy to hook up. I didn't need to use the ground lift switch so far, but it's nice to have the feature in case of any buzzing. The parallel high impedance output is a useful feature if you also need to send the signal to a nearby amp or processor at the same time.

The body of the box is really solid; I don't see it getting damaged easily. This thing is definitely worth the cost.

Relatively cheap and easy way to improve sound quality for any instruments (guitar and bass especially) by converting an instrument signal into a mic signal (through xlr). Sounds cleaner and less noisy. Everything is great, 4/5 stars on sturdiness because it does feel rather light for its size. Doesn't diminish its function.

It's hard to say much about a device with such a simple function, but it has lasted me quite a while without failing like the DI box it replaced. The ground/lift switch came in handy to eliminate a buzz in the system. It's hard to say what the sound quality is like. Though the sound coming from the PA seems to be less bright, it may just be the system and not the DI box. Anyway, it's a good way to connect an electric guitar straight to the PA's XLR jack (don't forget the amp/cab simulator).
