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.

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.

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

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

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 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.

Perfect fit, easy to install, good number of choices. The only downside is that you must keep the color coded package to identify the different flow amounts.
