To set the good faith tone for this feedback, I'm at the perfect point in my engineering career to be marketed more expensive, but more enduring "prestige" tools like Metmo is putting out. When I saw the ad for the multi-drive with the big leather pouch I could only say, "shut up and take my money." That said, it also means that I feel compelled to offer my manufacturing and human factors perspective on the product...
My starting constructive feedback on what appear to be quality control issues:
My grease marker stick in the multi-drive shipment box arrived broken (and it seems I'm not alone in this), which was disappointing.
It also appears that though my bit set addon contained the advertised number of bits, two types were missing and seem to have been replaced with duplicates of other bits: a second Philips PH0 instead of the PH000, and a second Pentalobe 1.5 instead of a Hex H0.9. More's the pity that the two bits I'm missing might be the ones I most need at this point.
One of the collets I received seems to have a small tolerancing issue on a corner of the hex cutout, but so far I don't think this impacts usability:
Finally, all but one of the brass tube sleeves in the larger leather pouch were set too deeply into the leather sleeve and had to be pulled out slightly in order for the graphite/grease sticks to not get stuck on the leather and actually be able to be removable after loading.
On the usability side of things, some thoughts:
I wish the stainless steel model had more texture. I ordered the stainless steel driver through the indiegogo campaign, and afterwards purchased the aluminum stubster through the store. While I get a kind of sensory satisfaction from fondling the smooth stainless driver form and its rotating end cap, it rapidly becomes a drawback when I end up trying to apply torque to anything with sweaty palms (which, I believe, is the problem a driver handle is attempting to solve). Even trying to fasten the 4mm adapter in the collet, it can be quite frustrating trying to ensure that I've spun the cap on tight enough to not be able to pull the adapter out. The knurling helps but especially on the cap, the knurled region is about half of the area it seems like it ought to be (to match the knurling on the handle), and I find myself wishing that the polished sections had even a fine satin texture that would give me a bit more friction like the aluminum handle does. I experimented in putting the aluminum cap onto the stainless handle (like a reverse black steel model) and the grip feeling is much improved. I did get the gripster addon but even that seems to start slipping around the handle before the torque needed to fasten the adapter is reached (and no, I don't seem to have gotten a rough collet like some people have).
I'd like the metal case lid to feel more secure. The metal case lid with magnetic closure is slick, but I feel like I'd like the perimeter chamfer to be a bit more aggressive because it makes me nervous it could slide off on its own if I'm just carrying it around by itself or otherwise not in the leather pouch. Even the leather tab meant to keep it from sliding out from the pouch tends to displace the lid from time to time. My ideal sensation would be that I can be secure that the lid will stay in place unless I'm deliberately prying it off. Also, the lid magnet on the bottom side (near the Metmo logo) tends to pick up the closest bit when reattaching the lid in some orientations, which is a little annoying.
Commercially, I understand some products are already in the works, but just to register my interest:
I'd like to be able to order more full-sized drivers without the complete kit, like how the stubster is now.
I'd like to be able to order individual 4mm adapters and scalpel holders!
I'd like to be able to order those before I convince myself to just order another driver set! 😛
