All this things teach us some lesson.
Here is my opinion and also note to myself & other who sells measurement device *wink* *wink*
(1)
Stating all the specification will not make my/our/your product becoming a professional product
but it should be mandatory to state all the fact and specification regarding the measurement device I/we/you sells to other people.
(2)
The specification said in #1 serves two purposes: to inform the buyer, what will they got AND to claim (or as a disclaimer) to whatever I/we/you sells.
For example if I/we/you were selling things with "about ±25% tolerance, sensor will smoke if laser is focused" mentioned,
then someone can't really protest if the sensor is smoked if he/she measures a focused laser IMO,
because it's already mentioned in specs, and customer should have agreed/acknowledge the specs when paying something.
(3)
It's better to sell cheap device but mentioned all the minus.
As for the LPM, this will let the buyer knows that the cheap LPM meant for "everyday approximation only" meter with so many limitation.
(4)
Stating "This is a sample. some place may not be perfect" is inadequate IMO,
should have been mentioned more detail about the minus or limitation.
(5)
As for coating, it took me about six month to find those carbon coating which has >480W/cm² damage threshold,
using no paint at all because all high temp paint i used is giving me a smoke lol.
Building LPM is rather easy, but making/finding the coating is not.
(6)
Calibrating can be easy, but it should be mentioned what's the reference sensor used, and which wavelength did the reference is calibrated to.
This serves just like a claim/disclaimer too. Because, you know, even those professional sensor don't have the spectral response for public.
Prove me wrong, but could you find the spectral absorbtivity for this particular Ophir product?: Ophir L30A-19mm-BNC.
I guess not
There is so many of Ophir model, they won't even bother to create all the graphs,
or did they try to hide it from us?
(7)
IF the pocket LPM from LPS is sourced from some creator (and not built by LPS itself)
then the LPS should give some push to the creator to improve or to give more detailed specs
(or maybe some clarification/revision, e.g from 15W to 4W LPM).
(8)
I know that doing dropshipping can be this frustating, especially if the suppliers claims too much,
If the worst happen, the buyer (or LPF's community) can only blame the seller which is LPS, not the real supplier/creator of the LPM.
It's inevitable
(9)
I'm sorry to hear all this, to tommy as a distributor, also laserbee, Lifetime17, and other who already paid.
I hope that pocket LPM can be improved in future,
the community needs a cheap tools, but not a combination of cheap+crappy tools (no offense intended)
Additionally:
- If anything can go wrong, it will.
- If there is a possibility of several things going wrong, the one that will cause the most damage will be the first one to go wrong.
- If anything just cannot go wrong, it will anyway.
- If you perceive that there are four possible ways in which something can go wrong, and circumvent these, then a fifth way, unprepared for, will promptly develop.
- Left to themselves, things tend to go from bad to worse.
- If everything seems to be going well, you have obviously overlooked something.
- Nature always sides with the hidden flaw.
