CORE sensor Omdömen 28

Le service client est très réactif et très à l'écoute. N'hésitez pas vous pouvez leur faire confiance !!

Received a faulty sensor as a Christmas present that was unable to pair with my phone. I've been unable to contact core for a replacement and my product is now listed as sold out

Bestel hier niks, mensen. Het zijn oplichters. Bestelling geplaatst; de site geeft aan dat als je vóór 12:30 uur bestelt, de bestelling dezelfde dag nog wordt verzonden. Na een paar dagen nog steeds geen track-and-trace ontvangen. Meerdere e-mails gestuurd, maar geen enkele reactie gekregen.

I returned my CORE device almost a month ago, and the refund has still not been processed. There was no notification from the company confirming they received my return, even though tracking shows it was delivered.

It took two emails just to get a return label, which took a week to arrive—and I had to pay for the return shipping myself. Overall, the lack of communication and the slow, inconvenient return process have been very frustrating.

Was really looking forward to trying product. Unfortunately after purchasing a few month ago the item still has arrived and Core are being unresponsive to my emails. Gutted. Please no one buy there product mine didn’t even come, no replacement sent or refund provided

Purchased the first version sensor for £230+VAT last year, was offered the option to upgrade to version two in for £154.67+VAT which I did March 27th.

New device still not arrived but showing as ready to be shipped May 2nd.

In all honestly, I achieve the 10/10 rating every session by wrapping up warm and executing 110 minutes on the trainer with a fairly hard start for 10 minutes. So the device is only re-confirming what I've "calibrated" in my environment. 7/10 takes around 24 minutes less (each +1 takes around 8 minutes). I like having the data point - but I'm sure I could achieve the same benefits without it indoors. Outdoors in a hot climate - it would be more beneficial.

Unreliability connects to the app. Data is lost or disappears at times. Sometimes doesn't connect to the watch. I've given two stars as when working I find some use for this.
But disappointed with overall purchase due to its unreliability. Went back and forward with their support who haven't really resolved at all despite being within its warranty period. I would recommend avoiding.

I have been using the Core Sensor for several months and the App has been improved significantly during this period. I find the graphs useful and like way the results are presented. The battery lasts several days and recharges in about three hours. Set up is quick and easy with the clips holding the sensor in place nicely. The results are great and customer service have been good at dealing with any issues. The only bad thing is the sensor is not compatible with Frontier X2.

It is an amazing tool that has helped prepare me for my Ultramarathon this summer. I am looking forward to continue working with it and integrating it into my training routine!

Sensor works well and seems very sensitive. It could easily recognise when I had Covid. But it is expensive and the updated App is basically not more clear/explicit than the previous version. Especially it's seems not possible to see you trend more than 24h which is a shame. Also the tutorials on how to use it and extract the maximum out of it is not very detailed.

To better elaborate here on "not being validated" - I'll restate that and state, it's not validated in athletic populations but has efficacy in clinical situations.

The current literature surrounding (which is minimal) the device does not fully support (sadly) the claims made on CORE's website, where depending on the intensity of the exercise, the device becomes increasingly unreliable. As it stands, I would advise athletes and coaches be aware if they do use the device - and like most things, more research is needed (independent studies, that is).

Amazing little device, lots of new features in the app, just need to learn how to make the best use of them all.

In actual use It's easy and comfortable to use.

Really useful and accurate data especially for my home training conditions here in Cyprus!!!

Me es muy útil para conocer cómo ha sido el esfuerzo y recuperarme para siguiente intervalo, también información preciosa sobre tu estado metabólico, peor recuperación más difícil alcanzar ciertas temperaturas centrales.

Works perfect. Provides new training opportunities

A perfect integration with garmin data

As advertised. The CORE device has opened my understanding to temperature based performance based metrics. I only wish I had bought it sooner!

Super interesting device and now with summertime even more
