What is going on it seems awesome but what is the story compared to quarq?
I don’t know how it compares to Quarq, but I have tested my P2Ms against my Powertaps on the same ride. I have an ample supply of P2M & PowerTap PMs and all of them are within a few watts of each other for my regular training loop. I use dual head units when riding, an Edge 500 and a 910 XT without issue. I would highly recommend either of these units to any of my friends. I have also owned SRM but am not a fan of the cadence magnet. I can’t recommend Rotor Power at this time.
I’ve had my P2M unit for about 9 months now. This is my first power meter, so I can’t compare to Quarq, but it reads consistently every ride. It just simply works. IMO its a great deal. The customer service during the buying process was top notch as well. Installation was quick and easy.
I have had my power2max for over a year now and I would recommend it to anyone who is looking for a good value in a power meter. In fact I intend on getting another one soon to replace my powertap wheel on my road bike.

I was set on a quarq until asking around Boulder about quarqs. The consensus (even from the guys that were given units) is that they are kind of expensive and have excellent customer service. You get to learn this because the odds of returning one is pretty high. Based on that I found p2m, but my figures of merit are slightly different as I only have one bike and a ton of wheels that make it fit the role of 4 different bikes (road, gravel, MTB, cyclocross). I already owned a set of S900 cranks so just ordered the P2Max spider w/o arms, but a complete crank is not much more $, if you don’t already have them, the deal on the praxis rings is excellent as well. My focus is 'cross so it is also valuable not to have extra stuff glued or zip tied to the frame (speed/cadence sensor, PT hub pickup) as it is one less thing to collect mud or break off. It shipped a couple of hours later and was at my door 4 days later. The install was easy - I think it was 3 screws and 7 bolts, took me 25 minutes, and that was with my 2 year old “helping” (my chain ring bolts were all placed inside the BB shell for me…). The only comment I have it you should install the battery before mounting the cranks back on the bike. Your hands get pretty nasty from handling parts in that region of the bike, might want to get some gloves or a bar of Lava. The unit paired instantly with the head unit and has behaved exactly like every other power meter I’ve used. I was trying to talk myself into a stages due to them being a local company, but could not get over the whole L/R split thing (like are you improving, or just getting better at using your left leg). I could not find a single negative review on the power2max type s like the idea that you just turn it on, go train and don’t have to spend much time messing around with calibrations, temperature compensations, etc. For me the power meter is a means not to totally suck at racing while keeping training hours in the single digits so work/family time can still happen.
I’ve had a Quarq on my tri bike for about 5 years now. Love it to death.
I’ve had a Power2Max on my road bike for about six-nine months or so.
If I had to get a new one, I would probably get another Power2Max due to price. It does left/right balance (0-179 right, 180-359 left) and the least expensive Quarq does not.
Either would do just fine.
I own two. They’re great. No hesitations to buying a third if need be.

Just went from powertap to P2M so that I can race with a disc. So far I’m very pleased. Just works. I even installed it myself (Type S Specialized FACT) with very little hassle.
I’ve had my P2max (FSA Gossamer) since last January and it has worked great.
$900 shipped for this quality product is really hard to beat.
I have 3 Powertaps, and while I also like their quality, I most likely will not be buying another one because the P2max is a better value.

I concur with everyone else in this thread. I’ve had mine for a little over four months and it is my first PM. Thus I cannot compare it to anything else. But as one person said… it just works.
Wow this is amazing for a company to have this many outstanding reviews in a row. Seems like no one has bad experiences with power2max. Thank you all for posting. I am going to be getting one soon. Question I have a Computrainer and I am planning on training inside a lot… Can I use the same number from my 20 min FTP test for both road power and inside power? Or should I do two different tests? I was planning on only getting numbers from the CT and not power meter on bike as I have a cheap trainer bike. Thoughts? I may need to post this else where.
Thanks again ST rocks

Same experience here, I have been using a powertap for 5 years and just replaced it with a P2M about 4 months ago. It has worked great, not the slightest problem, consistent measurement, and numbers are pretty much identical to what I get from my powertap (based on the rides i did with both). Highly recommended.
quarq is a great power meter and their customer service is great 
.
I’ll add one more positive review for the P2M. Like many others, I can’t say that I’ve owned any other power meters, but it just works. I use it with TrainerRoad and a Garmin 500 on the road and it’s all good. The battery is easy to replace and calibration is easy.
Edited to add: I’ve had mine about 9 months now.
another happy consumer here, had it about three months now.
I’ve had the P2M for several months and this is my first power meter. I have been able to compare power numbers to Wahoo Kickr on indoor rides and they are spot on. Wouldn’t hesitate to buy it again.

Ideally you’ll record your ftp and pace with the same power meter so as to eliminate variation amongst different meters (the power meters may be repeatable, which is what matters, but not necessarily accurate… computrainer might tell you 250w, powertap might tell you 260w for the same effort. If you do your ftp test on computrainer and then pace off the powertap you could be selling yourself a bit short.
Also, being able to see a power file from a race is quite valuable. Pacing is a skill that gets lost on most age-group triathletes IMO.
Just had my Type-S P2M installed prior to IMTX. Its been consistent and easy to pair with multiple head units. I did quite a bit of research and this seemed the best option to suit my needs at a great price. Haven’t had to deal with customer service yet, but from what I’ve read, if that happens I should be taken care of fairly and quickly. I’ve recommended the unit to anyone that asks without hesitation.
I have three training buddies that ride on them and as far as I know the units have performed very well over the 1-2 years they’ve had them. If i were in the power meter market I would seriously consider them against Quarq. My secondhand impression is that they just work and work repeatably.
Have had my P2M since January and it’s great. I’m new to power but it works well with TrainerRoad and also during races. It’s hard to beat the price when you’re on a budget.
