$ Why Thousands Less Than Dealer Pricing?
A complete clean R12i + R750 base/rover kit with TSC5 and TDL-450H from a Trimble dealer typically runs $32,000–$40,000+. Both receivers in this kit are RMA-flagged / in-house repaired, which means they cannot carry Trimble factory warranty — but the hardware is fully restored, tested, and ready to deliver the same RTK performance in the field.
If you don't need Trimble factory warranty support, this kit delivers the same field results for a fraction of dealer pricing. Same Maxwell 6 chipset, same 672 channels, same ProPoint engine, same RTK accuracy. Backed by our 3-month in-house warranty on the complete system.
⚠ Important — RMA-Flagged Receivers Notice
Both the Trimble R12i Rover and the Trimble R750 Base in this kit are RMA / In-House Repaired units. Please read carefully before purchase:
• Both receivers were previously flagged in Trimble's RMA system as replaced items
• Not eligible for Trimble manufacturer warranty — cannot be registered with Trimble for factory warranty
• Not eligible for Trimble factory service or support
• Not eligible for Trimble firmware option upgrades (additional bands, RTX subscriptions, feature unlocks must be sourced separately)
• Both receivers have been fully restored, tested, and verified in working order by our in-house technical team

• Backed by our 3-Month In-House Limited Warranty on the complete kit (receivers, controller, radio)
• The TSC5 controller and TDL-450H radio are NOT RMA-flagged — they are standard pre-owned items
If a Trimble factory warranty or factory service eligibility is essential to your purchase decision, this kit is not the right fit. By purchasing, buyer acknowledges the receivers' RMA-flagged status. Contact us with any questions before placing your order.

These are quality materials!
The design and materials are above average. They fit great and are so comfortable. I have nerve damage and need open toes. These work perfectly. The colors are cute and did not fade upon washing. I will definitely order more, now that I’ve received my “trial” set. lol

Absolute game changer for chronically dry feet/cracked heels
Size: S (up to size 7)-Beige
I had recently bought a pair of silicone heel/ankle wraps to fill out my boot a little since I noticed my heels were lifting when I was skating. I tested them out around the house and noticed they left my heels softer while the rest of my sockless feet got quite dry. So I got these full foot silicone socks to see the effect of having my whole foot covered. I slather the entirety of my feet with Dr. Scholl's Severe Cracked Heel Restoring Balm (love how convenient it is to apply it to my feet with the solid stick form) and then slip them into these silicone socks. After just a couple hours, when I pull out my feet they're (a teeny bit sweaty at first), but then overall soft and smooth and have absorbed the balm fully leaving barely any residue in the silicone sock. I find these silicone socks generally comfortable; I wear them in the evenings while relaxing on the couch, take them off after a couple hours and let my feet breathe a bit, and then reapply my balm and socks and wear them to bed. If I wake up in the middle of the night, which I almost always do (not because of the socks), I'll take the socks off and allow my feet to breathe again. I wear a woman's size 6 shoe and the small size is pretty comfortable. However, I made the mistake of wearing them while being on my feet for a couple hours straight during household chores -- they must've somehow cut off my circulation a bit with the standing, so I wouldn't recommend wearing these silicone socks while being active. And since they're not exactly my foot size, they slide around sometimes and will start to feel tight at my big toe. But if that happens, I just tug on the toe area of the sock to give my big toe more wiggle room and problem solved. Prior to wearing these socks, I was soaking and doing heavy duty exfoliation of my feet every week. These socks seem like they'll work to help me extend the time between soakings and exfoliations. The 5 pack is a great value. So far none have torn, so they seem rather durable. Not sure what I could even do to tear a hole in these.

EXCELLENT FEET MOISTURE PROTECTION
Size: S (up to size 7)-Beige, Size: S (up to size 7)-Beige
Why did you pick this product vs others?:
I have burns on my feet and needed something that I could put burn creme on and still walk around in with. I tried other silicone footsie but they would teae really easily. So far these are doing really well for this purpose. They are holding their shape too. The only caution I have is the same with all silicone footsies: They can be slippery on wet floors, so also wear with socks over them.
The biggest issues is when they say a size they mean it. The silicone used in these have little give in them, so they won't stretch out and loose their shape. That can be a good thing, or not so good, depending on how well they fit your feet and what your intent is with wearing these. The other issue is if they fit snug around those toes, that tends to be where the first tear in the material will happen. Because of how these are made, the tear is actually more like cracking in the material and once it occurs you won't be able to get much use out of the sock after that. If you are planning to wear them around the house or for long term use, I suggest going up a size or look for the toeless options.

Silicone socks
Size: M (up to size 9)-Beige
The socks are sized large. The quality of the silicone is good. But they slide around on your feet if you try to walk, making them difficult to use and a bit uncomfortable. Unless you are able to sit for long periods of time the likely will not work well. Recommend looking for a better value.
