Mainstays Blue Floating Collapsible Pool Chlorine Dispenser for Up to 3 in Tablets

I picked this up to handle the 3" chlorinating tablets for my pool, and it has been a fantastic addition. If you've used traditional floating dispensers, you know they can be bulky to store away during the off-season or when everyone is in the pool. The collapsible feature on this Mainstays model is a total game-changer—it compresses down flat, making it incredibly easy to tuck into a pool bin or shelf when it's not in use. When it's fully expanded, it easily holds standard 3" tablets. The adjustable chlorinating control ring at the bottom is sturdy and stays exactly where you set it, allowing you to regulate the chemical feed perfectly depending on your pool size and weather conditions. What I Like: Collapsible Design: Expands fully for deep-basket tablet capacity, but folds down flat for sleek storage. Sturdy Construction: The plastic feels durable and stands up well to both intense sunlight and constant chlorine exposure without fading fast or becoming brittle. Easy Adjustment: The twist-ring vents are smooth to turn but secure enough that they don't shift on their own. High Visibility: The bright blue top makes it easy to spot floating around the pool so you can quickly check when it's time for a refill. Bottom Line: You don't need to spend a fortune on a high-end chemical dispenser. This Mainstays one delivers excellent functionality, reliable chlorination, and the added bonus of space-saving storage. Highly recommended for any standard backyard pool setup!

[This review was collected as part of a promotion.] This is an absolute genius design. I love the ChemGuard glove on the lid, it makes placing the chlorine tablets such an easy task. You don’t have to worry about your skin touching the harmful chemicals. The basin holds 2- 3” inch tablets with ease. It also floats right at the perfect spot on the water line, it’s not too deep and not too low.
