My three questions would be...
1) What is its input impedance in ohms? 2) Why no FX Loop? 3) Why no mute button? The usual disclaimers apply......IMHO, YMMV etc.

hard to tell from the pic but it looks big.
Di boxes are like elephant traps . If you don't see any elephants they must be working. but i will agree that a mute is real nice. And although i couldnt find the spec for input impedance i am sure it can be had. I bought a real nice one from orchid sound awhile back . Their muting Di. Works as designed. No elephants..

I have never had a problem with any DI, passive or active, in 40+ years of playing (and that includes bottom of the line passive). DI technology is pretty old and I think it is safe to purchase them on their feature set.

If someone gave me one, I'd toss it in the gear bag along with my 5 other DI boxes. It's just a Direct Box not a preamp despite the 'active' circuitry…it's for matching impedance from ¼" high impedance in to XLR low impedance out. I like the ground lift, and signal attenuation (and phase reverse) capabilities…I have those on my passive DI boxes (not phase reverse). I own both active and passive DI boxes, and still gravitate to passive DI boxes as they are clean, and quick-n-easy to set-up. In fact I gave 3 active ones away to a church who uses the same basic stage/instrument setup all the time. They were big, bulky, and no better than the passive ones. I do like the 'built-like-a-tank' aspect of equipment, but those little toggle switches don't belong on tanks and break off pretty easy if dropped too many times (or stepped on).

All DIs do not perform the function of matching impedance. If you are running a passive piezo, you need a DI with a one meg input impedance. Otherwise you are sending your mismatched signal down the line.
