Smooth action, highly accurate and reliable, new favorite daily use pen. Shipped fast and discreetly, and best price around.

Its a nice pen…but not for me. I prefer clicking feedback and build quality i get with Novo and Juniorstar, Savvio’s quiet plunger action could be a win for some, but for me is disconcerting. Additionally, for reasons unclear, with Savvio I consistently have a drop wasted after i pull out the needle, no matter how long I wait.

Well it’s an original product what mean a high quality, only this was enough for me, it’s very smooth and very acurate, also it comes with the original case what is very cool from my point of view.

I love the Savvio. I prefer the red to the graphite, but the color does not affect the quality at all. Metal, smooth surface, lightweight, accurate, durable. With a good quality 3ml cartridge, Savvios are smooth with the dosing. The “ghost click” is nearly silent, which adds to the smooth experience.

This will be an unorthodox review. I purchased this pen and it arrived defective. I always assume within this space refunds are not a thing. For the price I paid I just offered it up to the peptide gods and moved on with my day, BUT I saw someone else talking about an issue and wanted to include my data as well in case it was a bad batch of pens and I could save someone else from the same problem and alert the owner to the issue. Not only did he reach out to me directly but offered me a path to resolution and refund. Ive been in this space a while and while customer service is nice, its not always available, its the reason I keep coming back to Daropep for my pens and recon supplies.

Smooth high quality pen. Love the look and feel of them. I bought both colors. Graphite for me and Red for my wife. Easy to use and dosage is accurate from my rudimentary home testing. Case is a bonus especially for travel. Fast shipping and great customer service. Will be using Daro Pep for all my pen and pen supply orders!

I’ve been using the Savvio for about a week. It’s a pretty good pen. It probably has one of the smoothest manual actions of any pen that I’ve tried. Those include the V1, V2, V4, and Xulin. Sometimes I found myself looking at the plunger to see if I was indeed pushing it down. It’s silent so you don’t get the auditory or tactile click like many of the others. That’s going to be a personal preference. It’s extremely light and seems to be well made. Is it worth the price over the others I’ve tried? I guess that’s debatable. If you are a budget-minded person, look elsewhere. If you don’t mind spending a little extra on quality, I don’t think you will be disappointed. The pen is supposed to not let you dial more units than what is left in the cartridge, but according to my testing it was not accurate. Let’s say the pen only lets you dial it to 50 units; you may only get about 35 units with the injection. The same applies to the Convipen and Gansulin pens, which are the other two with this feature that I’ve tested. I thought it was worth noting. The pen shipped extremely fast from Daro. Overall I am please with the purchase and purchase experience.

Just to clarify, the accuracy issue is only with that final dose based on the number of units the pen lets you dial. Otherwise, the Savvio pen was always accurate in my tests. Sorry, I couldn’t edit my previous review.
