What is the M-420?

The Marsden M-420 is a lightweight, portable adult floor scale. It’s an easy to use scale, virtually identical to our M-430 Floor Scale, but has a much higher accuracy (50g increments as opposed to 200g). This makes it perfect when a highly accurate weight reading is required.

Why should I choose the M-420 over the M-430?

The M-420 and M-430 are both robust, portable floor scales. They are both Class III Approved and MDD Approved, therefore approved for weighing in a medical environment for the purpose of monitoring, diagnosis and medical treatment.

Where they differ is in their accuracy. The accuracy of the scale you use should be determined by what you are using it for. The 200g accuracy of the M-430 is suitable for many applications, however for more serious applications - such as weighing children, or weighing adults for critical treatment, the 50g accuracy of the M-420 will be more appropriate.

The 50g graduations will allow you to get a much clearer picture of changes in patient weight.

Who uses the M-420?

The M-420 is ideal for all hospital wards and departments, with its robust build suitable for constant daily use. Accuracy to 50g means nurses can get high accuracy weight readings for monitoring, treatment and diagnosis purposes. This high accuracy is also essential when weighing diabetic patients, calculating weight for specific antibiotics, for prescribing medication and for weighing children.

What other features does the M-420 have?

The M-420 is covered by the Marsden 4 Year Warranty.

This easy to use floor scale has a non-slip surface, with a robust casing meaning it can withstand years of use. It's light enough to be portable, too, and an optional carry case is available.

To use the scale, simply tap the surface with your foot and it switches on. The digital weight reading can be reversed, so it can face towards or away from the user. The Hold function means the weight reading stays on the screen even after the patient has stepped off.

The M-420 also has a BMI feature - you can enter the height of the patient, and then, when the scale reads the weight, BMI is automatically calculated.

Wireless connectivity is available for this medical weighing scale, meaning weight data can be instantly transferred from the scale to a central patient database, via mobile, tablet or PC. This makes the M-420 ideal for speeding up patient weight data capture, and makes it the perfect professional scale for telehealth initiatives.

The scale is powered by 6x AA batteries for over 100 hours of use (6000 weigh ins).

Nice, but not great fabric quality
Color: Floral Black, Size: Large
The fit was great. Colors were as shown. The fabric shows signs of wear pretty much on the second wear so durability isn’t great. The fabric is soft and light weight so perfect for spring and fall. Not sure I’d buy again as I think it will look worn out quickly.

Very Straightforward and Easy to Use
Reload type: One Time Reload
I have used this several times, and it has always been a smooth and convenient experience. The biggest advantage is how intuitive the process is. Reloading the balance is simple, quick, and easy to understand without unnecessary steps or confusion. It is especially useful for managing spending, setting a shopping budget, or keeping funds ready for future purchases. Instead of entering payment details every time, having balance available makes checkout faster and more convenient. I also appreciate how quickly the funds are applied, allowing immediate use once the reload is completed. This is one of those simple Amazon features that works exactly the way it should. Overall, easy, efficient, and user-friendly. I have been very satisfied with it. Five stars.

“ incredibly convenient”
Reload type: One Time Reload
I recently used the Amazon.com Gift Card Balance Reload option, and I’m thoroughly satisfied with the process and the overall experience. Here’s my detailed review: Convenience The Gift Card Balance Reload feature is incredibly convenient for anyone who shops frequently on Amazon. It allows me to add funds directly to my Amazon account without having to go through the process of entering credit card information every time I make a purchase. This is perfect for those who prefer to manage their shopping budget by preloading funds to their account. It saves me time and makes the checkout process smoother. Ease of Use Reloading my gift card balance was quick and easy. All I had to do was go to my Amazon account, select the “Reload Your Balance” option, and choose the amount I wanted to add. The process is simple and user-friendly, with clear instructions. You can choose to set it as a one-time reload or opt for an automatic reload at regular intervals, which is an excellent feature for those who want to stay on top of their shopping without worrying about running out of funds. Reloading Options One of the best aspects of this feature is the flexibility in reloading amounts. I can reload any amount I choose, whether it’s a small amount to cover a single purchase or a larger amount for future shopping. There’s also the option to set up an auto-reload, so my balance is automatically replenished when it drops below a certain threshold. This is particularly helpful for frequent Amazon shoppers, as it ensures there’s always enough funds available without having to manually reload every time. Processing Time Reloading my balance was instantaneous, and I was able to make purchases immediately after adding funds. The money is applied to my Amazon account almost immediately, so there’s no waiting around for it to process. This makes it ideal for urgent purchases or spontaneous shopping. Security The Gift Card Balance Reload option is secure, and I have peace of mind knowing that my payment information is kept safe through Amazon’s encrypted systems. I don’t have to worry about storing credit card information for each transaction, and the reload process is secure and straightforward. I also appreciate that I get an email confirmation every time my balance is reloaded, providing an extra layer of security and transparency. Value for Money The Gift Card Balance Reload is a great option for managing your Amazon shopping budget. It doesn’t come with any additional fees or hidden costs, and I get exactly what I pay for. Plus, I can take advantage of any promotions or bonuses Amazon may offer for gift card reloads (e.g., occasional bonus offers or discounts). The ability to add funds as needed without being locked into a set amount of money is very useful and cost-effective. Overall Impression I’m highly satisfied with the Amazon.com Gift Card Balance Reload service. It’s a fast, easy, and secure way to manage your shopping budget and ensure that you never run out of funds on Amazon. The process is simple, and I love the flexibility in choosing how much to reload, as well as the option for automatic reloading. For anyone who frequently shops on Amazon or wants to manage their spending more effectively, this is a great tool to have. I will definitely continue using this feature to make my Amazon purchases even more efficient and hassle-free.

Easy and simple: Exact Step-by-Step Guide to Reloading Your Balance
Reload type: One Time Reload
I found reloading my Amazon gift card balance much easier than expected. The process was simple and took about 5 minutes at most. Here are the exact steps to do it: ​Login: In the Amazon app or on Amazon.com, log in to your account. ​ Menu: Tap the 3 lines on the bottom right corner of your screen (next to Rufus, Amazon's AI). ​ Find Category: In the section highlighted "Shop by category," tap on Gifting & Registry (3rd option down in that section) and a drop-down menu will appear. ​ Select Gift Cards: On the drop-down menu, tap Gift Cards (first option). ​ Choose Your Action: "The Gift Card Shop" will appear. There you will have three options: "Redeem a gift card," "View your balance," and "Reload." ​ Start Reload: To add funds, tap Reload. ​ Select Type: Scroll down to "Add funds directly to your Amazon Gift Card balance" and tap which reload type you want (one-time, low balance auto-reload, or scheduled auto-reload). ​ Enter Amount: Choose your reload amount. The default is $25, but you can type in your own amount as well (the minimum amount is $5.00). ​ Finish: Tap the orange "Buy Now" tab. ***I used the Amazon app using the u i OneUI version 8.0 these Amazon app on Android version 16 (Baklava) on a Samsung Galaxy S25 Ultra. Others may have a slight variation of the menu setup on the Amazon app.***

Easy way to add balance
Reload type: One Time Reload
Reloading my Amazon gift card balance has been easy and convenient. I like using it when I want to keep a little money set aside for Amazon orders or make checkout quicker without thinking about which card I want to use. The process is straightforward, the balance shows up fast, and it has been reliable every time I have used it. It is also helpful for budgeting because I can add a set amount and then use that balance for regular purchases. Nothing complicated about it, which is exactly why I like it.
