Puzzling online shopping experience

1. After placing the order I was expecting a confirmation but No! Nothing! Weird! Suspicious!
2. Getting back on their website the cart was not updated and it showed differently multiple times and finally the cart was empty.
3. Why I visited the website multiple times? There's No responses from the Live Chat at all even nothing the next day. Isn't it ironic? So I started to decide the order cancellation based on 1 & 2.
3. No responses for the previous messages or processing the cancellation.
And the transaction is pending through the coming Monday. Otherwise no signs of updates on the order from them.

We’re sorry to hear about your experience and understand why this was frustrating.

Order confirmations are sent automatically immediately after an order is placed, and we have not received reports of this issue from other customers. We recommend checking your spam or promotions folder, and also confirming that there wasn't a typo in the email address entered at checkout, as either of these can prevent the confirmation from being received.

Regarding the lack of response, yesterday was a federal holiday in observance of Independence Day, so our team was out of the office. We apologize for the delay and appreciate your patience. Please rest assured that taking care of our customers is our highest priority, as reflected in the thousands of 5-star reviews we've earned. Our team will be following up with you shortly to address your concerns and ensure everything is resolved.

Thank you for bringing this to our attention, and we appreciate the opportunity to make this right.

Should be able to edit your purchase and delivery information on the site.

Good customer response when I mentioned that I submitted the wrong address for delivery, however, after I was told my address was corrected, it did not change on the site and it went to the incorrect address.
You should be able to edit your purchase and delivery information on your site.

UPDATE November 30, 2025. We have implemented an easy way for customers to edit their address for up to two hours after an order is placed. This can be done from the post purchase email you receive, the Order Confirmation page or when you login to your Order History: https://account.living.fit/orders

ORIGINAL REPLY
Thank you for taking the time to share your feedback. We really appreciate it, and I want to clarify what happened with your address change so you know exactly where things went wrong.

When you reached out, our team let you know that we would do our best to update the address. Because this item ships directly from one of our third-party partners, we are not able to edit the order ourselves once it enters their system. In this case, the vendor shipped the package very quickly, which meant the address could not be updated in time even though we tried to intervene before it went out.

We understand how frustrating this is, and we are reviewing how we communicate these situations so expectations are clearer moving forward. We are also exploring better ways to allow address updates when possible, although this can vary based on the vendor.

If there is anything else we can do to help with this order, please let us know. We want to make it right.

6 dial-adjustable resistance levels: Turn the resistance valve left or right to dial airflow load on inhalation and exhalation -- progress with you as fitness improves.
Mouthpiece-based design: Compact silicone mouthpiece with seated plastic valve creates an optimal seal for breath training -- not a mask, no head strap.
Targets diaphragm + intercostals: Strengthens the primary respiratory muscles to support deeper, more efficient breathing and improved lung volume threshold capacity.
Football helmet adapter compatible: Optional adapter attaches the AEROSx to a football faceguard so players can train respiratory load during drills and route work.
Lightweight + portable: Small enough to take anywhere -- training kit, gym bag, or office desk -- to support 5-minute daily warm-up or cool-down sessions.
Three colorways: Black, White, Red. Easy clean -- rinse under the tap or wipe with mild detergent.

The AEROSx Respiratory Resistance Lung Trainer is a compact mouthpiece-based breath training device from TrainingMask. Unlike the elevation masks, the AEROSx is not worn over the face -- it is a silicone mouthpiece with a seated plastic valve that sits in the mouth and creates resistance against both inhalation and exhalation. A single turnable dial offers 6 adjustable resistance settings so training intensity scales with fitness level over time.

The device targets the diaphragm and intercostal muscles -- the primary respiratory muscles -- to build strength and endurance through repeated loaded breathing cycles. Regular use is associated with improved lung volume threshold capacity, deeper and more efficient breathing, improved oxygen utilization, and faster recovery between training sessions. The AEROSx pairs with an optional football helmet adapter that attaches to a faceguard so football players can incorporate respiratory load during drills, routes, and game-simulation training.

The AEROSx is lightweight and portable enough for daily use during warm-up or cool-down (5 minutes is the recommended starting protocol). Cleaning is straightforward -- rinse the mouthpiece under the tap, or wipe with a mild detergent or disinfectant wipe and air dry. Available in Black, White, and Red colorways.

Q: What is the AEROSx and how is it different from an elevation mask?
A: The AEROSx is a mouthpiece-based respiratory resistance trainer -- a silicone mouthpiece with a seated plastic valve that sits in the mouth. Unlike the Training Mask 2.0 or 3.0, it is not worn on the face. It targets the diaphragm and intercostal muscles directly through breath-by-breath resistance.

Q: How many resistance levels does it offer?
A: 6 dial-adjustable resistance settings. Turn the resistance valve left or right to dial airflow load up or down. Resistance applies on both inhalation and exhalation.

Q: How long should I use it per session?
A: TrainingMask recommends 5 minutes per day to start, typically added to a warm-up or cool-down. The device is small enough to take anywhere.

Q: What is the football helmet adapter?
A: An optional adapter that attaches the AEROSx to a football helmet faceguard, allowing players to incorporate respiratory load during drills, route work, and game-simulation training.

Q: How do I clean the AEROSx?
A: Rinse the silicone mouthpiece under the tap, or wipe the exterior with a mild detergent or disinfectant wipe. Pay close attention to the resistance valve area and air dry before storing.
