New Funk Firm Achromat Warped

No warpage on my FF mats.  Not using the adhesive stickers. 

FYI there is a 1200 specific Funk Firm mat. The platter on the 1200s is slightly smaller diameter therefore a standard mat won't fit inside of the ridges of the platter.  Of course you can place the standard Funk mat on top of the supplied rubber mat as I'm doing.

Yes, I received the SL1200 mat. Wow, I never thought of placing the FF mat over the rubber mat. That’s a lot of height, but of course the VTA is easily adjustable on the SL1200G. Either way it is still warped.

Ok just checking cuz I didn't know myself until trying and doing some research. 

Putting one mat on top of the rubber mat is absolutely crazy.
This how SAEC SS-300 looks directly on Technics platter, no bubber.
Resonance in the 200-400Hz range is common to most of the rubber mats, they must be avoided. 

P.S. never seen a warped mats, just return it for full refund

I want to return it for a replacement.

Mine is flat but I remember reading about at least one other that arrived warped.I am sure Music Direct will replace it with no issues.

It was shipped in a rather weak bendable cardboard mailer. For $155 It should have been shipped in regular LP packaging. 

I have several of the Funk Firm mats and all of mine are perfect.  I have never needed or used the adhesive discs.

One of my favorite mats.

I agree that you really shouldn't use these on top of another mat.

Music Direct is sending me a replacement mat. They were very accommodating.

Hi! 
Was the replacement mat ok?
Just asking cos I went through 3 and they were all warped (5mm thickness ones). However I flattened the last one a bit and have been using it as it really helps in tightening up the bass on my thorens. However the warp when combined with slightly warped records can become audible . I have also measured a negative effect with adjust+ software. The warp worsens speed variations quite considerably. So my problem is that  I really like the bass and added clarity the mat gives but the warp is becoming annoying. Are there any other mats I could try that are not as expensive but yield similar results?

The replacement mat was also warped. Music Direct accepted the second return and we gave up. I now use a Herbies Mat as a did before on my Rega P3-24.

Maybe the Vinyl Flat LP product would cure the mat's warp?

The warps must have something to do with the newer mats?  I have (2) of the 3mm and (2) of the 5mm, all of which are perfectly flat.  I bought these years ago and have never had a problem.

@mofimadness  Yes, I think it is definitely a manufacturing or quality control problem. Also, both times the mat was delivered in a flimsy cardboard package. I told MD that they should ship the mats in regular LP boxes.   

I have a 3 and  a 5mm and both are perfectly flat, no adhesive needed.

The 5mm is only about 18 months old so qc on them was good at that time.

sounds like something has gone sadly wrong.

i actually bought mine from England as even with shipping it was a fair bit cheaper than music direct
