I only have to recharge about every three weeks on this and the original collar. I have had no issues with the battery because I am not constantly overcharging it. My original collar is still going strong. I have been using it over a year. The dogs stay within the boundary without any problem. They are both Vizsla's, and love to chase birds and anything else that moves. They have never run through the fence. They even stay in the boundary when I accidentally let them out without the collar. I have had no issues with water, and the dogs are often out in the rain. I will update if anything changes, but so far I'm happy with the system. Review: Our second collar - We purchased an IUC-4100 a couple years ago when our pit bull grew large enough to leap over the (4 foot tall) fence (he likes to go make new friends... with everybody). We quickly trained him to the system, and it has worked great for us. At our new house, our other dog (who could never leap a fence and thus had never needed a collar) discovered a way out of our new fenced yard where our fence and the neighbors fence could not quite meet due to a concrete retaining wall. So we purchased this collar for him. Since the collars work by listening for a radio signal transmitted by the fence, there was zero installation necessary--just charge it and go. Other reviews mention some durability issues--with our first collar, we have had no such problems. Our pit bull even got it off once and used it briefly as a chew toy; other than some teethmarks in the plastic, it still works great. I have installed the system at 3 houses now and it has worked great every time. ## Features - Extra collar receiver with ReadyTest function to ensure a proper fit - For use with Innotek's IUC-4100, IUC-4200, and IUC-5200 systems - Delivers electronic stimulation dogs quickly learn to avoid - Low-battery indicator; collar fits neck sizes 8 to 24 inches - Receiver measures 2-3/4 by 3/4 by 1-1/4 inches; limited lifetime warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000A7GM3C | | ASIN | B000A7GM3C | | Age Range Description | All ages | | Brand Name | PetSafe | | Color | beige | | Customer Reviews | 3.8 3.8 out of 5 stars (76) | | Date First Available | May 7, 2008 | | Date First Available | May 7, 2008 | | Department | Racks/Futons | | Department | Racks/Futons | | Directions | Innotek UltraSmart Extra Collar Receiver for IUC-4100, IUC-4200, and IUC-5200 Systems | | Included Components | Innotek UltraSmart Extra Collar Receiver | | Item Dimensions LxWxH | 3 x 6 x 9 inches | | Item Package Dimensions L x W x H | 9.5 x 6 x 3 inches | | Item Weight | 1.44 ounces | | Item model number | IUC4225 | | Item model number | IUC4225 | | Manufacturer | Training and Bark | | Manufacturer | Training and Bark | | Number of Items | 1 | | Product Dimensions | 3 x 6 x 9 inches; 1.44 ounces | | Size | One Size | | Target Audience Keyword | dogs | | Warranty Description | Limited Lifetime Warranty when purchased from a PetSafe Authorized Retailer.

We 'upgraded' our old system with the Contain and Train system and had nothing but problems. I currently have two English Setters, and these collars are horrible. They do not stay buckled and fall off the dogs when they play. We had to start putting a zip-tie on the collar so that it would stay on the dogs. They do not charge reliably and only work for about 6-9 months before they won't take a charge. The system is also very prone to interference from other dog fence systems. We had a lot of issues with our neighbors fence 'cancelling' out our signal on the side of our property adjacent to their property with a different system. (The fence was professionally installed according to the specs.) When we could keep the collars on the dogs, they would crap out and I would have to return them for a new collar about every 9 months. After a two years of this nonsense , we installed the Invisible Fence system and it works brilliantly. The collars are small and made with a very sturdy nylon strap. If you love your dog, do not get an Innotek system. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/2390095-innotek-ultrasmart-extra-collar-receiver-for-iuc-4100-iuc-4200](https://www.desertcart.tn/products/2390095-innotek-ultrasmart-extra-collar-receiver-for-iuc-4100-iuc-4200) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-27*
