Can it increase the upf of a shirt that already has some upf rating? For example can it increase a 30 upf rated shirt to a 40 or 50?

Is the shirt made of Cotton? This product only works on cotton and must be washed in the hottest water possible. It will not work on polyester. This may not completely answer your question. In my experience most products already containing a UPF are not cotton.

Yes, the settings are easily adjustable to any strength you prefer. It's really easy to figure out this machine. You can use setting one and with the push of a button you can change it to a higher strength. :)

This was a birthday gift for my son. I dont't believe his lifting reaches that limit, so not an issue for him. But, I see the conflicting info. I'd try a direct call to to manufacturer and ask for clarification, unless someone else knows. Can probably Google xmark fitness and get the phone #.

Mine ends in 008 but I purchased it longer than 3 months ago. I have no idea what the new UPC might be. Ask the manufacturer to be sure.

We haven't seen any difference in the shirts. My husband wears an X large though so could be a difference in the smaller sizes.

Not sure. I did not buy the shirt with spf in mind. If this is not specified on the amazon product description try the Exoffficio website. This is one of my favorite and most worn shirts.

I believe it said 50 on the tag when I got my shirt. It says 50 in the product description. You can also Google the Columbia website to double check.

I tried it only on t-shirts. It works magic. Unfortunately, I never tried on anything else. Good Luck!

As I understand it, it will reset the level to full regardless of whether you refill it ot not. I am not sure however because I have never done that. (I don't know why you would want to do that though.

I do not believe so. I do not see any way to raise it. It is very comfortable though.

I checked my shirts and no SPF rating is mentioned. You might try the Exofficio website and direct the question to them.

Yes you can increase the volume and it also alerts you when you are midway of the work interval ( pre-set by you). These allows you the option of switching sides or during the interval workout. However, I'm not aware of being able to select nor change the default sound options. Nonetheless, if you are getting down and burning those fat cells, that's enough music to.my ears and gladness in my heart. Enjoy, have fun and be well.

You start with 25, which can be upgraded to 50, 100, or 250. There are no other intermediate steps.

This is more for clothes that have turned yellow.. This will add more blue to your clothes.

If you mean can you add more units past the 4th unit, I don't know. I only have the 4 units that came with it. It is my understanding that it would be possible to add as many units as you wanted, based on how it works though. But I can't honestly say.

It doesn't add HP. It alters the frequencies and deepens the tone. Basically cleans up the sound especially if you have headers.
