Prasacco 10 Pcs Water Flow Restrictor 1.5/1.8/2.0/2.5/3.0 GPM Shower Head Flow Control Valves Water Flow Saver Adapter Set for Fixed Shower Head or Handheld Shower (14.2 x 13.8 x 5.3 mm - Small)

They are easy to install. The various options allowed me to adjust the water pressure from my bathroom sinks and shower.

Looking at the package I could not identify the flow rates for each piece. I had to come back to the product page to look at the color code. Printing the color code to keep with the package for future reference

Initially I was disappointed that I had to pay for an entire variety pack to fix one shower faucet, but I'm glad I did since until trying a couple I didn't know which volume was best for my situation. Liked it so much I changed the kitchen faucet reducer for a larger volume one. Shower now works great, saves water, and at not too bad an expense. Fast shipping as usual.

My wife is happy to have stronger water pressure. I’m happy because I could tune the shower gpm to what we use and still have good pressure without running out of hot water too quickly. Settled on 3gpm and works great, wife is happy.

All this filters are plastic with mesh and rubber borders. Back water pressure bends the plastic and filters get destroyed after 2 month. Search for shower metal regulators if you are trying to control pressure

I tried a yellow one for 3-4 showers and decided it wasn't the right pressure for me. I noticed it was pretty deformed after just a few showers. In the photo it's next to the other (unused) yellow one. So I'm not sure how long these will last. I can't remember which color I ultimately settled on, but it does the job. However, it's a bit noisy and the water sometimes surges and backs off a bit. It's hard to describe. Inconsistent flow.

These work great. I removed the flow restriction from my new showerhead wand because the flow was too low (1.5gpm). While it felt awesome without a restrictor I was worried about a high water bill since is was running at about 4.5gpm. I’ve tried the 3gpm one and I can barely tell the difference, which is a good thing. I may even go down to 2.5 or 2 to save water.

I bought this pack of flow restrictors after getting rid of the flow restrictor that came with my shower head. I recently moved, keeping my shower head with me, and the water pressure was too much in my new place. I was losing a lot of hot water quickly. I installed the 2.5 gallon flow restrictor on my shower head. The water pressure is perfect and I can enjoy my hot shower now. The downside is that now my shower head makes an annoying whistling sound, not sure if this can be resolved. Other than that, I’d recommend this product whether you’re trying to conserve water usage in general or conserve the hot water in your water heater tank.
