Invyr UHMWPE Switch Linear Stems V2

Dec 12, 2020

Hi Everyone, Update time again. Sorry this one came a little bit later than expected. We have been hard at work trying to fix the issues. Since last time I spoke we have tried some new inserts in the moulds for the poles, this has alleviated some of the angle deformation, but not completely. I don’t think it’s to the point where we can call it acceptable just yet, however it is a definite improvement. We are going to try a couple more revisions in regards to this. I’ll let you know the results. This is the before and after from this process:

In addition to the pole revisions we are also going to revise the distance between these two faces again:

The hope is that a tighter tolerance will keep the stem in a more upright position. It's obviously just a balancing game though, as you know, depending on the housing used the sizes can all be slightly different, resulting in some combinations working better than others. If we push the size of the stem too large then it may not be compatible with some of the smaller switch housings, which would be less than ideal. Sorry that this has been taking a little longer than expected but I would far rather fix all the issues while we have the chance. This is a little rundown of the process that we go through each time we make a change to the mould:

Proposing the modification to the switch factory and/or discussion about the viability
Switch factory contacts the mould factory about changes that need to be made
Mould is transported to the mould factory for modification
Mould is modified
Mould is then transported back to the switch factory where it can be tested
Test results are reported to me and then further discussion with switch factory

If something isn't up to standard or wrong it needs to go back through that process which can usually take up to a week, and that on the faster side since we are being given priority at the moment. I hope this gives you an idea of where we are currently at. We are continuing to work as fast as possible in resolving this issue. Regards, zisb

zisbThank you for all the updates on the matter! I would love to get the new ones ASAP, but I appreciate all the effort you are putting in to avoid another fiasco.

zisbTo everyone: If it isn't obvious, this December 11th update shows that we're not ready to produce the stems, so the previously quoted 6-8 week delay is not relevant/realistic. I can say, "wait another 6-8 weeks", but realistically the answer is, they'll be ready when they're ready, and we're not going to rush it. But it could be 1, 3, 5, 10 more back and forths before things are 100% ready to go. @zisb will keep the updates coming though!

zisbWill these stems bottom out due to the pole or the bottom of the stem?

zisbTake your time. I'm very patient... as long as it's not summer 2021.

outerSpace3Seems like it could be at this rate. This product shouldn't of been sold if they were this far away from making usable stems.

KevinI am honestly confused. Wasn't the stated issue that the manufacturer made the stems out of spec? I don't understand this months long process of "improving" the stem design. All I can take away from that is the original design was heavily flawed. And, as mentioned, it should have never been sold in the first place.

rchan00xGroup buys exist because people are willing to take the risk to back/support/fund the development of a new product designed by a creator. Anyone signing up for these stems (which have never been seen, reviewed, etc.) is trusting that Zisb (not Drop, we're just the middleman) is bringing a good product to market. Zisb has a reputation, having produced multiple high quality community loved products in the past, and his design for this new stem has been described. My rough interpretation of the situation is that the usability, with poor manufacturing, is unacceptable (hence the returns/refunds/etc). If it were manufactured to better specification, the product works- but maybe isn't all that great. I think Zisb is taking the opportunity here to change the moulds so that the final product exceeds "acceptable" given the learnings he's had having observed the moulding and production results. It's crucial to understand that manufacturing is really hard- and honestly, shouldn't even exist at the group-buy scale. In this case, I think it's the materials that are not behaving the way that they were expected (all plastics deform, change shape, shrink, etc. after cooling from the mould. Each plastic deforms differently and millimeters of variances matter). At a professional corporate scale, multiple moulds would be made and tested first, before going to market. This basically never happens for a community run group buy (because it's much too costly). The fabulous (and generally understanding) Mech Keys community is generally willing to support/back creators and front the cash to make ideas turn into reality, knowing these risks. This situation is showing you the unfortunate side when the product designs don't work out as expected. Having seen Zisb's previous work, I have full faith that he'll eventually figure something out, and the value of Zisb (and the community) using Drop.com is we'll protect your money in case things don't work out.

Kevin"Anyone signing up ... is trusting that Zisb (not Drop, we're just the middleman) is bringing a good product" Here we go again with the persistent insistence that Drop has zero culpability. "We're just here to collect commission, don't expect us to do anything other than skimming some money as the middleman" People don't use middlemen because they have too much money, or are incapable of talking to the other end of the transaction. The commission taken by a middleman is payment for their consultation service providing industry knowledge and connections. Part of that industry knowledge is vetting the business and product in question. That is where you failed, you did not properly vet this product as a middleman. You sold us on this product. Read your description, you literally told us how great it is, and gave us reasons to buy it. And now you're just throwing your hands up saying you have zero responsibility after marketing it to us. Good luck to everyone else who still uses this website, I'm just here until this product gets settled and I'm not looking back.
