Excellent product
Great product to connect electric cables Saves you time amending the cables and replaces terminal connectors make it easy and safe for electric connections. They are small and the price is very attractive Used them in my living room and dinning room ceiling lights and in seconds all was safely connected Recommend 5* product

A must for any major rewiring prject..
Great product if you're doing extensive DIY rewiring work. Easy to use, makes for a great connection and probably the best product of its type on the market. I have used 100's of these over several years & never experienced a problem or failed connection.

Wago are the best
Used for a lighting rewire, makes joining cables very easy and fool proof, much better than chock blocks, must have for a diyer, just fit and forget. The same size nut can handle several thickness wires. Good value pack.

I was against these at first, prefering screw connectors, gave them a try, very handy.
After a few uses with projects, I've changed my mind, relatively easy to use in projects. WAGO verse Screw connectors. WAGO; quick & easy to connect. Screw; find the correct screw driver, some connectors have a clamping plate that needs to be lifted, getting the wires into the connectors. (Yes can be the same with WAGO) I have not done any tests for current/overheating. Max amps is 2A or 3A so far. All my projects are low current/signal/temp connections. For permanent higher current I still prefer screw. I have now used 2/3/4/5 way WAGO connectors, some temp are permanent now. LOL. Will update in future

Makes wire connections so much easier
These connectors are very good. I used them for a specific I had and it was literally clip and replace. A delight to work with.

The best connectors on the market, i have been using wago connectors for 25 years, these lever type 221s are relatively new, about 3 yrs on market, i have been using them since they came on market, great wago quality, good variety of sizes and capacities, both in ca le numbers and current carrying capacity. Can be used on all cable types, solid ,stranded or flexible conductors. Compact in size and transparent so you can see tgat conductor is in correct position. Tou will not regret buying these connectors, but beware of cheaper asian knock offs which are rubbish.

I'm incredibly happy with this purchase. Previously I used waterproof wire-nuts for my irrigation timer wire for my sprinklers. The wire nuts would somehow fall off; it seemed every time the gardener came. I tried a couple of other brands of quick-connect; including one that did not require any spicing and had built in waterproofing; but they proofed unreliable. I've had great success with the WAGO 221 in-line connectors. They were super easy to install and I like that they are reusable. I was able to water proof them with the WAGO Gelbox 207. I found that one gelbox held 3 connectors and I needed a separate gelbox to hold the groundwire connector where I used the 5 terminal version. (I only needded 3, but ChatGPT recommended I get the 5 for dependability). At first I thought it would be difficult to deal with seperate in-line connectors and gelbox for the water proofing; but after doing the installation I can say this was the easiest and fastest of the solutions. My connections feel solid, protected and if I ever need to change the wiring I can do so without buying new connector hardware! Also I was concerned that the gel boxes would be too big or cumbersome, but that turned out not to be the case at all. The gel boxes fit nicely around the connectors are are not bulky.
