do the needles on the roller dull with use or do I need to replace?

Nancy - yes, needles do lose their edge after a few months of use. This is when you want to get a replacement. You'll feel it.

The needles dull after about a month. I have yet to buy another one, but eventually will.

I personally use each blade for a week/seven days before swapping it out for a new one. I've used them for longer and they start to dull after that.

The needles are in a circular pattern with one in the center. I broke the center needle and was going to replace it but it works even better without the center needle.

I use my regular needles but I have to lighten up on the tension so its not so tight and breaks the thread. Hope this helps.

Hi Mary, I've only used mine a couple of weeks so I'm not sure, but the roller still seems brand new. I just blow it off and clean with the brush they send and I foresee it lasting several months at the least.

The roller may is defective if it is leaving behind a residue. The residue is harmless and can be easily removed with a soapy sponge or isopropryl alcohol.

my understanding is that you are only supposed to use it twice a week, every 3 days or so in order to give the collagen time to produce. I'd find it hard to imagine that the needles would dull very quickly especially because you roll lightly. I'm guessing a roller would last 1 year easily and then replace it all together.

I saw replacement rollers when I ordered this. The company that makes the roller does sell them. Try looking at the description for the roller and the replacements should be on the page somewhere

Yes, the needle is replaceable. In fact, you can get replacement needles at Amazon. Here's the link:http://tinyurl.com/mmthg9h

I can't give you a definite answer because I am not sure but one thing I can definitely assure you on is that it rusts. This is extremely bad as your skin is being punctured and the last thing you need it rust particles getting in your pores. Just rather buy a different roller. One that the needles are made of titanium.

I believe they are graphite powder used on the rollers. I advise you to read the maintenance guide to verify and I wouldn't use it until it is required or recommended by the manual.

I purchased mine a few months back and am not all that impresses. The rollers tend to skip and leave marks and yesterday, the blades started to leave gouge marks on the wood. Will have to take it apart to see what's up.

Esthela, maybe t there's something stuck inside, or wound around the roller or brush? Otherwise, I have no idea. Good luck!

Yes, they get dull after 3 months heavy use or 6 months of lite use at this time the blades should be changed

It has been my experience the roller does not need replacing just cleaned properly. Good luck!

That's the only way I use them. But they DEFINITELY work better with the roller. No tip necessary tho.
